Sharp quadratic $χ$ -binding functions for powers of bipartite graphs

Arpan Sadhukhan, Suraj Kumar Sahoo

For every natural number $r \geq 2$ , we construct $r^{t h}$ powers of bipartite graphs whose chromatic number is quadratic in their clique number, showing that the straightforward qu…

The boxicity of the compressed zero divisor graph of the ring of integers modulo N

L. Sunil Chandran, Suraj Kumar Sahoo

The boxicity of a graph $G$ , denoted by $b o x (G)$ , is the minimum integer $d \geq 0$ such that $G$ is the intersection graph of axis-parallel boxes in $R^{d}$ . The class of ze…

Learning Regularizers: Learning Optimizers that can Regularize

Suraj Kumar Sahoo, Narayanan C Krishnan

Learned Optimizers (LOs), a type of Meta-learning, have gained traction due to their ability to be parameterized and trained for efficient optimization. Traditional gradient-based…

Boxicity of Zero Divisor Graphs

L. Sunil Chandran, Suraj Kumar Sahoo

A $d$ -dimensional box is the cartesian product $R_{i} \times \dots \times R_{d}$ where each $R_{i}$ is a closed interval on the real line. The boxicity of a graph, denoted as $b o x (G)$ , is…
