Intersection Patterns in Optimal Binary Doubling Subspace Codes
Anirban Ghatak, Sumanta Mukherjee
Subspace codes are collections of subspaces of a projective space such that any two subspaces satisfy a pairwise minimum distance criterion. Recent results have shown that it is po…
A Generalized Epidemiological Model for COVID-19 with Dynamic and Asymptomatic Population
Anirban Ghatak, Shivshanker Singh Patel, Soham Bonnerjee +1
In this paper, we develop an extension of standard epidemiological models, suitable for COVID-19. This extension incorporates the transmission due to pre-symptomatic or asymptomati…
Extending Coggia-Couvreur Attack on Loidreau's Rank-metric Cryptosystem
Anirban Ghatak
A recent paper by Coggia and Couvreur presents a polynomial time key-recovery attack on Loidreau's encryption scheme, based on rank-metric codes, for some parameters. The secret ma…
Optimal Binary Projective Space Codes from Maximal Partial Spreads
Anirban Ghatak
Recently a construction of optimal non-constant dimension subspace codes, also termed projective space codes, has been reported in a paper of Honold-Kiermaier-Kurz. Restricted to b…
Subspace Codes for Random Networks Based on Plücker Coordinates and Schubert Cells
Anirban Ghatak
The Plücker coordinate description of subspaces has been recently discussed in the context of constant dimension subspace codes for random networks, as well as the Schubert cell de…
Codes on Lattices for Random SAF Routing
Anirban Ghatak
In this paper, a construction of constant weight codes based on the unique decomposition of elements in lattices is presented. The conditions for unique primary decomposition and u…
Evolutionary Stability Against Multiple Mutations
Anirban Ghatak, K. S. Mallikarjuna Rao, A. J. Shaiju
It is known (see e.g. Weibull (1995)) that ESS is not robust against multiple mutations. In this article, we introduce robustness against multiple mutations and study some equivale…
