Title: Mixed Multiplicities I and II
Abstract: Given a Noetherian Local Ring, with a maximal ideal $m$,
we will present the definition and existence of Mixed Multiplicities of
filtrations of $m-$ primary ideals. We will show that this mixed
multiplicity for general filtrations satisfies the standard theorems and
inequalities for mixed multiplicities for $m-$ primary ideals including the
Minkowski inequalities.

Title: Poincare' series of divisors on surface singularities.
Abstract: We associate a Hilbert function to the exceptional components of a resolution of singularities of a surface singularity, and study its structure. We consider the question of when its associated Poincare' series is rational.

Title: Local Uniformization, Defect and Associated Graded Rings
Abstract: We discuss the problem of local uniformization (resolution of singularities along a valuation). We define the defect of an extension of valued fields and show that it is the only obstruction to local uniformization in positive characteristic. We explain how defect can be seen through lack of finite generation of associated graded rings along the valuation.

- Title: Control of wave equation.
Speaker: Debanjana Mitra,
Time: Friday, 16-11-18, 4p.m.-5p.m.
Venue: Ramanujan Hall, Department of Mathematics, IIT Bombay.
Abstract: In this talk, we will prove the observability inequality for
wave equation in the case of localized interior control.
Then the control of wave equation with variable coefficients will be
discussed.
