Möb Homogeneous Analytic Hilbert Modules over the Bidisc

Jyotirmay Das, Somnath Hazra

An analytic Hilbert module over the polynomial ring, consisting of holomorphic functions over the bidisc, is said to be Möb-homogeneous if the corresponding pair of m…

Representations of the Möbius group and pairs of homogeneous operators in the Cowen-Douglas class

Jyotirmay Das, Somnath Hazra

Let Möb be the biholomorphic automorphism group of the unit disc of the complex plane, be a complex separable Hilbert space and be the grou…

Penalizing Proposals using Classifiers for Semi-Supervised Object Detection

Somnath Hazra, Pallab Dasgupta

Obtaining gold standard annotated data for object detection is often costly, involving human-level effort. Semi-supervised object detection algorithms solve the problem with a smal…

A Family of Homogeneous Operators In The Cowen-Douglas Class Over The Poly-disc

Prahllad Deb, Somnath Hazra

We construct a large family of positive-definite kernels $K: \mathbb{D}^n\times \mathbb{D}^n \to \mbox{M} (r, \mathbb C)$, holomorphic in the first variable and anti-holomorphic in…

On analytic structure of weighted shifts on generalized directed semi-trees

Gargi Ghosh, Somnath Hazra

Inspired by natural classes of examples, we define generalized directed semi-tree and construct weighted shifts on the generalized directed semi-trees. Given an -tuple of direct…

Homogeneous Hermitian Holomorphic Vector Bundles And Operators In The Cowen-Douglas Class Over The Poly-disc

Prahllad Deb, Somnath Hazra

In this article, we obtain two sets of results. The first set of complete results are exclusively for the case of the bi-disc while the second set of results describe in part, whic…

Semi-Lexical Languages -- A Formal Basis for Unifying Machine Learning and Symbolic Reasoning in Computer Vision

Briti Gangopadhyay, Somnath Hazra, Pallab Dasgupta

Human vision is able to compensate imperfections in sensory inputs from the real world by reasoning based on prior knowledge about the world. Machine learning has had a significant…

A product formula for homogeneous characteristic functions

Bhaskar Bagchi, Somnath Hazra, Gadadhar Misra

A bounded linear operator on a Hilbert space is said to be homogeneous if is unitarily equivalent to for all in the group Möb of bi-holomorphic automorphisms of…

Homogeneous -shifts

Somnath Hazra

The classification of homogeneous scalar weighted shifts is known. Recently, Korányi obtained a large class of inequivalent irreducible homogeneous bi-lateral -by- block shif…
