Speaker: Rajula Srivastava, NISER

Title: Graphs and Colourings

Abstract: Simply put, a graph is nothing but a set of points ("vertices"), along with edges which connect them. A planar graph is a special type of graph- one where the edges do not cross each other ( i.e., meet only at the vertices). In this talk, we will discuss an interesting problem in...

Date/Time: Thursday, March 30, 2017 - 14:30 to 15:30

Speaker: Prof. Bart De Bruyn, Ghent University, Belgium

This will be the fourth lecture of a series of five on Finite Fields.

Date/Time: Thursday, March 30, 2017 - 10:35 to 11:30

Speaker: Nabin Kumar Jana, NISER, Bhubaneswar

Title: Radon-Nikodym theorem and conditioning

This is the second lecture on this topic with the following:Abstact: Radon-Nikodym theorem of measure theory was proved in 1930 and A. N. Kolmogorov laid the foundation of modern probability in 1933 where the formal played a crucial role. In this Short Lecture Series in Mathematics (SLSM), we...

Date/Time: Monday, March 27, 2017 - 11:30 to 12:30

Venue: Mathematics Seminar Hall

Speaker: Somnath Basu, IISER Kolkata

Title: Geometric models of coverings of graphs

We shall discuss covering spaces of graphs, leading to facts about subgroups of free groups.We shall then construct geometric models, inspired by these graphs,and analyze some concrete examples.

Date/Time: Friday, March 24, 2017 - 15:30 to 18:00

Speaker: Somnath Basu, IISER Kolkata

Title: How many pentagons are there in a football?

We shall discuss Gaussian curvature and total curvature. We would then interpret this notion of total curvature in a combinatorial way. This would lead us to an answer to thequestion in the title. The talk will be elementary and self-contained.

Title: Radon-Nikodym theorem and conditioning

**Abstact:** Radon-Nikodym theorem of measure theory was proved in 1930 and A. N. Kolmogorov laid the foundation of modern probability in 1933 where the formal played a crucial role. In this Short Lecture Series in Mathematics (SLSM), we discuss the conditioning of probability...

Venue: Mathematics Seminar Hall

Speaker: Vaibhav Pandey, NISER alumnus

Title: Some weirdly well behaving rings

We consider certain rings of smooth functions on a nice space, like a circle, and try to explore its algebraic nature using the smoothness of these functions. As a motivation for this, recall the ring C[0,1] of continuous real valued function on [0,1]. Recall how we prove that its maximal ideals...
