Title: Bass Note Spectra of Locally Uniform Geometries

Abstract: We formulate and report on the problem of the bass note spectrum of an invariant operator as one varies over locally uniform geometries. In the Euclidean setting this recasts classical problems of Mahler from the geometry of numbers in a new light. For certain operators, homogeneous dynamics can be used decisively. In the non-Euclidean setting of hyperbolic manifolds we review some recent developments using the conformal bootstrap method and random covers to study the bass note spectra. We highlight the theme and impact of rigidity.

Lecture 3 : (Commutative Algebra/Algebraic Geometry seminar)

Title: The intervention is efficacious, but will it be acceptable in a
real-world setting?” Welcome to the world of Implementation Science

Abstract : "Intervention science is a multidisciplinary field that focuses
on the design, implementation, and evaluation of interventions aimed at
improving health, social, or behavioral outcomes. These interventions can
include drugs, devices, and even policy-level or economic interventions.
While research studies continue to demonstrate successful interventions
that improve healthcare, their dissemination remains relatively slow.
Multiple studies show a significant gap between the adoption of effective
interventions in practice, which, if addressed, could result in a decrease
in human suffering, reduced mortality, and ultimately, an improvement in
public health.

In this talk, we will explore the science of implementation science,
particularly through the lens of randomized controlled trials (RCTs). We
will address the challenges of implementing and disseminating
interventions, illustrating key points with practical examples. Hybrid
effectiveness-implementation studies provide a promising approach by
simultaneously evaluating both the effectiveness of interventions and the
processes of their implementation in real-world settings. Throughout this
discussion, we will highlight both the challenges and successes of
implementation efforts across diverse contexts. By emphasizing the
importance of effective implementation, we can ensure that health
interventions deliver their intended impact, ultimately improving health
outcomes and advancing public health objectives."

Title: Harnack Estimate for Non-Homogeneous Parabolic Equations

Abstract: In this talk, we present a scale-invariant Harnack inequality
for certain non-homogeneous parabolic equations within a suitable
intrinsic geometry influenced by the nonlinearity. This result, in
particular, establishes Hölder continuity. Additionally, we discuss a
Harnack-type estimate on a global scale that provides a quantitative
formulation of the strong minimum principle. The talk is based on joint
work with Vesa Julin.

Speaker Bio:  Vedansh Arya has been a postdoctoral researcher in the
Department of Mathematics and Statistics at the University of Jyväskylä,
Finland, since 2022. He completed his Ph.D. in Mathematics at the TIFR
Centre for Applicable Mathematics, Bangalore, in the same year. His
research interests span regularity theory for elliptic and parabolic PDEs,
unique continuation problems, free boundary problems, and mean curvature
flow.

Lecture 4 (Commutative Algebra/Algebraic Geometry seminar)

Speaker: R.V Gurjar

Time, Day,Date,Venue: Thursday 9th Jan, 11:30 am in Ramanujan Hall

Title: 2 new proofs of Zariski's Main theorem

Abstract: This lecture will supplement the lecture series by Prof.
Nitsure. In this talk Prof. Gurjar will discuss two new proof of Zariski's
Main Theorem, substantially different from the proof of Peskine discussed
by Nitsure in his first lecture.
