Towards the characterization of minimum weight codewords of Schubert codes
Mrinmoy Datta, Tiasa Dutta, Trygve Johnsen
A conjectural formula for the minimum weight of Schubert codes was conjectured by Ghorpade in 2000. This was established by Xiang in 2008. In 2018, Ghorpade and Singh provided a ne…

The second minimum weight of Grassmann codes
Mrinmoy Datta, Tiasa Dutta
We give an independent combinatorial proof of Nogin's Theorem concerning the minimum distance of the Grassmann codes using a special decomposition of the Grassmannians. We use the…

Remarks on second and third weights of Projective Reed-Muller codes
Mrinmoy Datta
Determining the weight distributions of the projective Reed-Muller codes is a very hard problem and has been studied extensively in the literature. In this article, we provide an a…
