Generalized Grötzsch Graphs
Ashish Upadhyay
The aim of this paper is to present a generalization of Grötzsch graph. Inspired by structure of the Grötzsch's graph, we present constructions of two families of graphs, and…
A Direct and New Construction of Near-Optimal Multiple ZCZ Sequence Sets
Nishant Kumar, Sudhan Majhi, Ashish K. Upadhyay
In this paper, for the first time, we present a direct and new construction of multiple zero-correlation zone (ZCZ) sequence sets with inter-set zero-cross correlation zone (ZCCZ)…
A Direct Construction of 2D-CCC with Arbitrary Array Size and Flexible Set Size Using Multivariable Function
Gobinda Ghosh, Sachin Pathak
Recently, two-dimensional (2D) array codes have been found to have applications in wireless communication.In this paper, we propose direct construction of 2D complete complementary…
On -Additive Cyclic Codes
Cristina Fernández-Córdoba, Sachin Pathak, Ashish Kumar Upadhyay
In this paper, we introduce -additive cyclic codes for . These codes can be identified as -submodule…
New Classes of Quantum Codes Associated with Surface Maps
Debashis Bhowmik, Dipendu Maity, Bhanu Pratap Yadav +1
If the cyclic sequences of {face types} {at} all vertices in a map are the same, then the map is said to be a semi-equivelar map. In particular, a semi-equivelar map is equivelar i…
Semi-equivelar maps on the surface of Euler genus 3
Debashis Bhowmik, Dipendu Maity, Ashish Kumar Upadhyay +1
If the cyclic sequence of faces for all the vertices in a map are of same type, then the map is said to be a semi-equivelar map. In this article, we classify all the types of semi-…
