Title
A theorem of Bruns on free resolutions of ideals generated by three elements
Abstract
Let R be a commutative Noetherian ring. In 1972, P. Cohn proved that for every finitely generated R-module M, there exists a three-generated ideal I of R such that pd(M)=pd(R/I). In this series of two talks, we will see a generalization of Cohn's result due to W. Bruns. We will show that "every" finite free resolution over R is a free resolution of a 3-generated ideal of R.

Title Alexander Grothendieck: his life, his mathematics, and his writings.
Abstract
Alexander Grothendieck was arguably the most original, influential, and the most prolific mathematician of the 20th century. After retiring from active mathematics in his early 40's, he contributed to several newer fundamental insights. This lecture will reflect on some of the enigmas around him, before and after “retirement".

Title
The central limit theorem (CLT) for integrated density of states (IDS) of discrete random Schrodinger operator (Anderson model on lattice)
Abstract
First, we will define the random Schrodinger operator on the Hilbert space of square summable functions on the d-dimensional integer lattice, and discuss its spectral properties. Also, we will talk about the integrated density of states (IDS). Now, we will consider the existence of the integrated density of states (IDS) as analogous to the law of large numbers (LLN). Then, we will prove the analogous central limit theorem (CLT) when test functions are either polynomials or first-order differentiable with polynomial growth.

Title
Regular elements of semi-simple algebraic groups
Abstract
We will discuss a variety of topics in Algebraic groups through reading some of the papers that have become classics in the subject. The first few seminars will be on the paper by Robert Steinberg, Regular elements of semi-simple algebraic groups Publications mathématiques de l’I.H.É.S., tome 25 (1965), p. 49-80
