National Mathematics day : 22nd December 2021

National Mathematics day  is celebrated on the birth anniversary of Srinivasa Ramanujan. It is celebrated across the nation to acknowledge the contributions  and excellence of Ramanujan in the field of Mathematics.

As Ramanujan has majorly contributed in explaining the analytical theory of  numbers, the department of Mathematics has organized

Expert Talks on “Number Theory and its Applications” as part of Ramanujan Day on 22.12.2021 & 23.12.2021.

Dean E&T in his felicitation address, said that the National Mathematics Day on Ramanujans birthday is not just a tribute to his achievements  but also a way to keep his legacy alive and inspire the coming generations of Mathematicians from  the country.

DAY -1

Date & Time :

22nd December

02.00 PM IST

Resource Person:

Prof. Martin Milanic

Faculty of Mathematics,

Natural Sciences and

Information Technologies,

University of Primorska,

Koper, Slovania.

Topic:

On CIS Circulants

Prof. Martin Milanic started the session with Circulant Graphs and explained about the classes of circulants in the literature. He defined cliques, stable sets, CIS graphs, bull graph, complete graphs, complete bipartite graphs and the operations which preserve CIS property. He explained the classes of CIS graphs with examples. He explained about CIS d- graphs and its applications in combinatorial game theory. Further he explained about  Vertex -transitive CIS graphs, Paired Circulants, 2-Paired Circulants and its open problems for research.

 

DAY -2

Date & Time:

23rd December

02.30 PM IST

Resource Person:

Prof. Xiao-Jun Yang

College of Mathematics,

China University of Mining and Technology,

Xuzhou, China.

Topic :

“On Nontrivial Zeros for the Ramanujan Zeta Function”

Prof. Xiao-Jun Yang started the session with power series expansion for the entire Ramanujan Zeta function along with the work of Mordel. He detailed about integral, product representations and functional equations and theorems for the entire Ramanujan Zeta Function and about Hardy hypothesis.  He concluded the lecture with open problems of the work.

More than 150 faculty members and research scholars from all over the world participated in the program.  It has opened new avenues for the participants to explore.
