Interpolation Problem and Recent Studies on Demailly’s Conjecture (May 03, 2025)
Abstract: The fundamental question raised by Masayoshi Nagata (1958), inspired from the ‘Classical Interpolation Problem’ is a long-standing problem in the literature, which is: Given a finite set of points in the Projective Plane, what is the minimal degree of the hypersurface passing through those points with multiplicity at least m? G. V. Chudnovsky provided a conjectural bound to the above problem in 1981, but for the Projective Space of any dimension, and a year later J. P. Demailly generalized Chudnovsky’s work. These conjectures have an equivalent version in terms of understanding the lower bounds for the Waldschmidt constants of the ideal defining the points. We study Demailly’s Conjecture for the case m=3. I will introduce the Conjectures and then discuss the tools we have used in our study of Demailly’s Conjecture.

Interpolation in Projective Spaces (April 18, 2025) [Lightning Talk]
Abstract: In N-dimensional Projective Space, the main problem of interpolation is about finding the minimal degree of homogeneous polynomial that vanishes on a finite set of points with a given set of multiplicities. To deal with such a problem G. V. Chudnovsky and J.P. Demailly provided some conjectural bounds to the minimal degree, which I will discuss in the lightning session.

Interpolation of Projective Points under Algebraic Lens (April 05, 2025)
Abstract: The classical Interpolation problem of estimating new data from a set of known data is well understood under one variable situation. That has been modified for multiple variables also, using different techniques. Here we are more interested in higher dimensional Projective Spaces, where we are trying to find the lowest possible degree of the hyper-surface passing through a given set of points with prescribed multiplicity. There are famous conjectures to tackle such problems: Chudnovsky’s Conjecture, Demailly’s Conjecture, etc. I will be discussing those conjectures and some recent developments in this area.

Interpolation Problem: Conjectures & New Developments (January 03, 2025)
Abstract: Classical Interpolation problem of estimating new data from a set of known data is well understood under one variable situation. There are modified numerical methods of estimation, even for multiple (but small) variables. In higher dimensional spaces (namely, Projective Space) the main problem is of finding the lowest possible degree of the hyper-surface passing through a given set of points with prescribed multiplicity. To tackle such problems there are some famous conjectures: Chudnovsky’s Conjecture (provides the lower bound for the degree of the lowest possible hyper-surface that passes through the given set of points at least once), Demailly’s Conjecture (similar to the Chudnovsky’s Conjecture, but it captures the multiplicities also), and etc. I will be discussing those conjectures and some recent developments in this area, also some connected well-famous problems associated to interpolation problem.

Recent Developments in Interpolation Problems & Demailly's Conjecture (November 05, 2024)
Abstract: The classical Interpolation problem is a numerical analysis problem that estimates new data, from a known data set. There have been different approaches to provide more refined numerical results on Interpolation, like Polynomial Interpolation, Spline Interpolation, Mimetic Interpolation, etc. But in higher dimensions (specifically in Projective N-Space), the main problem is to find the minimal degree homogeneous polynomial that vanishes on a finite set of points with a given set of multiplicities. To deal with such a problem G.V. Chudnovsky and J.P. Demailly provided some conjectural bounds to the minimal degree, which I will discuss in my talk. I will also talk about some recent developments on this topic.

Overview of Generalized Interpolation Problem, and its Algebraic Components (May 24, 2024)
Abstract: The problem of interpolation is well known. But what happens when we leave planer space and move to some general space? While investigating such a problem, G. V. Chudnovsky gave a conjectural lower bound for the minimal degree of a homogeneous polynomial in the Polynomial ring that vanishes on a given finite set of points with a given set of multiplicities.
Later Waldschmidt Constant came into the picture, but how this famous geometrical problem boils down to the Containment Problem of Symbolic Powers and Ordinary Powers and how other associated problems developed is the primary objective of my talk. I will start with the basic overview of Algebraic Geometry and connect it to my research via Commutative Algebra.

Generalized Interpolation Problems and Chudnovsky's Conjecture (April 25, 2023)
Abstract: The problem of interpolation is well known. But what happens when we move to a higher dimension space over any arbitrary Field? While investigating such problem, Gregory Volfovich Chudnovsky gave a conjectural lower bound for the minimal degree of a homogeneous polynomial in the Polynomial ring that vanishes on a given finite set of points with a given set of multiplicities. Later Waldschmidth Constant came into the picture, but how this famous geometrical problem boils down to the Containment Problem of Symbolic Powers and Ordinary Powers is the primary objective of my talk. I will also talk on some recent developments in this area.

Abstract: Quadratic Gauss Sums, more known as Arithmetic Gauss Sum, first made appearance on 'Disquitiones Arithmaticae' in the 4th and 6th proof of 'Quadratic Reciprocity' back in 1797. Thereafter it became a powerful tool in Number Theory, and around 1870 Camille Jordan(probably) came up with a new Algebraic Structure with finite number of elements, what we now know as Finite Fields (appeared in 'Théorie de Galois'). And more than 100 years later people (namely, Prof. Ronald J. Evans, Prof. Bruce C. Berndt) tried to unify these two notions. In this talk, we will try to get the glimpse of this unified concept and explore some of its applications.
