Effective lockdown and role of hospital-based COVID-19 transmission in some Indian states: An outbreak risk analysis
Tridip Sardar, Sourav Rana
There are several reports in India that indicate hospitals and quarantined centers are COVID-19 hotspots. In the absence of efficient contact tracing tools, Govt. and the policymak…
Assessment of Lockdown Effect in Some States and Overall India: A Predictive Mathematical Study on COVID-19 Outbreak
Tridip Sardar, Sk Shahid Nadim, Sourav Rana +1
In the absence of neither an effective treatment or vaccine and with an incomplete understanding of the epidemiological cycle, Govt. has implemented a nationwide lockdown to reduce…
Behaviour of Finiteness of the Set of Associated Primes under Ring Extensions
Rajsekhar Bhattacharyya
We study the behaviour of the finiteness of the set of associated primes of local cohomology modules, more generally of Lyubeznik functors, under various ring extensions. At first,…
Synchronization in counter-rotating oscillators
S. K. Bhowmick, Dibakar Ghosh, Syamal K. Dana
An oscillatory system can have clockwise and anticlockwise senses of rotation. We propose a general rule how to obtain counter-rotating oscillators from the definition of a dynamic…
Exact Multi-Restricted Schur Polynomial Correlators
Rajsekhar Bhattacharyya, Robert de Mello Koch, Michael Stephanou
We derive a product rule satisfied by restricted Schur polynomials. We focus mostly on the case that the restricted Schur polynomial is built using two matrices, although our analy…
Exact Multi-Matrix Correlators
Rajsekhar Bhattacharyya, Storm Collins, Robert de Mello Koch
We argue that restricted Schur polynomials provide a useful parameterization of the complete set of gauge invariant variables of multi-matrix models. The two point functions of res…
