SRMAP Departmental Events

Progressing with the series of Departmental Seminars, Department of Mathematics, SRM University-AP, Andhra Pradesh invites Dr Gaurav Bhatnagar, Visiting Associate Professor, Department of Mathematics, Ashoka University to deliver a lecture titled “The Partition-Frequency Enumeration Matrix” on March 10, 2021, at 3 PM.

The Partition-Frequency Enumeration (PFE) matrix is an infinite upper-triangular number-theoretic matrix that is used to enumerate partition-like objects as an elementary approach. This matrix unifies voluminous results connecting number-theoretic functions to partition-type functions. The calculus is extended to arbitrary generating functions and functions with Weierstrass products. As a by-product, some well-known recurrence relations for many number-theoretic functions are recovered. These include the sum of divisors function, Ramanujan’s $\tau$ function, sums of squares and triangular numbers, and $\zeta(2n)$, where $n$ is a positive integer. As an application, Ramanujan’s famous congruences $p(5n+4)\equiv 0$ (mod $5)$ and $\tau(5n+5)\equiv 0$ (mod $5)$ are embedded into an infinite family of such congruences. During the lecture, Dr Gaurav Bhatnagar will highlight two other congruence results concerning the sum of the divisor function.

SRM University-AP, Andhra Pradesh has collaborated with the Indian Institute of Remote Sensing (IIRS) -Indian Space Research Organization (ISRO)’s outreach programme, enabling the students of SRM University-AP to avail the 74th IIRS outreach programme titled “Satellite based Navigation: A Journey from GPS to Mobile Phone Platform” sponsored by the Indian Space Research Organisation, Department of Space, Government of India. This programme is scheduled for March 1-12, 2021 and will be held from 4 PM till 5.30 PM.

In the modern era, an enormous volume of geo-spatial data is acquired from various sources, which is further processed for various studies on earth’s resources. These geospatial datasets require secondary data in the form of geo-tagged samples, Ground Control Points (GCPs), and ground-based large scale maps, which can be acquired using Global Navigation Satellite System (GNSS) technology. Apart from its applications in precise positioning, GNSS has applications in various areas such as Total Electron Content (TEC) estimation, earthquake studies, atmospheric studies, and mobile Geographic Information System (GIS).

The 74th outreach programme is committed to impart the basic information about the GNSS, followed by the studies carried out in different related areas. At the end of this course, participants will be able to comprehend the use of GNSS receivers with different measurement and positioning techniques as per the application requirement.

The Department of Biological Sciences, SRM University-AP, Andhra Pradesh has taken an initiative to organize the SRM-AP Biology Seminar Series – 2021. During the series, prominent scientists in the field of Biology from India and abroad will deliver a lecture every month through the virtual platform. The lectures are designed to encompass various topics on modern Biology to inspire scientists, undergraduate and postgraduate students, PhD scholars, and faculty members.

Prof Amitabh Joshi, Professor and Chairman, Evolutionary and Organismal Biology Unit, Jawaharlal Nehru Centre for Advanced Scientific Research in Bangalore, India, will be delivering the opening lecture of the series on February 27, 2021, at 11 AM. The erudite professor will be illuminating the audience on “Why evolution is central to both biology and our lives”. In this talk, Prof Joshi will address some of the misconceptions pertaining to evolution, and illustrate that evolutionary Biology is a very well-established and verified body of scientific knowledge. He will also demonstrate that an evolutionary perspective is not just central to Biology as a discipline, but also capable of addressing several unrelenting societal problems. Further, Prof Joshi will mention some of the significant Indian contributions to the development of evolutionary thinking over the past three to four decades.

Prof Joshi attained PhD in Genetics (1993) from Washington State University, Pullman. He then worked as a postdoctoral fellow with Laurence D Mueller at the University of California, Irvine (1994-96). He has been a Fellow at the Institute of Advanced Studies, Berlin, in 2001. Prof Joshi’s current research interests are in life-history evolution population dynamics, and he uses a combination of experimental approaches and theoretical work using computer simulations to carry out evolution studies of fruit flies. Also, he has worked on the evolution of extreme ecological specialization, and the evolutionary maintenance of sexual reproduction.

Prof Joshi has also served the editorial boards of Resonance, Journal of Genetics, Journal of Biosciences, International Journal of Evolutionary Biology, and Journal of Theoretical Biology. He is presently the Editor-in-Chief of the Journal of Genetics. In addition, Prof Joshi is a Fellow of all the three national science academies of India. He has been awarded the Shanti Swaroop Bhatnagar Award (Biological Sciences) in 2009, and the Lakshmipat Singhania-IIM Lucknow Young Leader in Science and Technology (National Leadership Awards) in 2010. He is also a J C Bose National Fellow. Recently, a new ant species discovered from Kerala has been named after Prof Amitabh Joshi.

Department of Mathematics, SRM University-AP, Andhra Pradesh presents departmental seminar on “Introduction to Homogenization Problem and Tartar’s Method”. During the session on February 17, 2021, at 5.30 PM, Dr Ravi Prakash, Assistant Professor, Departamento de Matem ́atica, Universidad de Concepci ́on, Concepci ́on, Chile, will describe this mathematical theory that has been introduced to explicate the behaviour of composite materials used by the material scientists. He will illustrate this model by drawing example of a homogenized material.

The aim of ’Homogenization’ is precisely to give the macroscopic properties of the composite by taking into account the properties of its structure. For a good understanding of this area, one must have a definite knowledge of Distribution Theory, Functional Analysis, Measure Theory, and Differential Equations.

The theory of Homogenization has reaching applications in several areas (including composite materials) such as porous media, analysis of their structures, etc. During the session, the esteemed guest lecturer will enable the audience to comprehend how Tartar’s Method uses two scales for the characterization of the material – the microscopic one, describing the heterogeneities, and the macroscopic one, describing the global behavior of the composite.

CSE organises webinar on “Nanonetworking in the Terahertz Band (and Beyond): From Nanomaterials to Macrosystems”

Department of Computer Science and Engineering organises a webinar on “Nanonetworking in the Terahertz Band (and Beyond): From Nanomaterials to Macrosystems” on February 20, 2021, at 7:00 PM IST. Dr Josep M Jornet, Associate Professor, Department of Electrical and Computer Engineering, Northeastern University, USA, is the distinguished speaker for the webinar.

Abstract: The possibility to control matter at the atomic and molecular scale opens the door to new physics, which can be leveraged into developing new types of devices with unprecedented capabilities. For the Communication community, the plasmonic properties of nanomaterials and nanostructures enable the development of miniature transceivers and antennas, which
intrinsically operate in uncharted spectral bands. The extremely small size of the devices and the unprecedentedly large bandwidths that these can excess opens the door to transformative applications across scales. In this talk, the state-of-the-art technology in electromagnetic nano communication and networks will be presented by following a bottom-up approach. The fundamental physical properties and capabilities of novel plasmonic transceivers, antennas and antenna arrays at terahertz and optical frequencies will be described. The propagation properties of the generated electromagnetic waves and their implications for practical communication systems will be presented. Starting from the hardware capabilities and the channel peculiarities, innovative solutions at the different layers of the protocol stack will be discussed, all defining a roadmap that can transform over ten years of fundamental research into meaningful societal applications.
