Using the Event Horizon Telescope (EHT), the gravitationally lensed rings around the supermassive black holes (SMBHs) in Messier 87 (M87) and Sagittarius A* (Sgr A*) have now been successfully imaged at a resolution under 10 gravitational radii (R$_{

Complexity and Structural Results for the Hull and Convexity Numbers in Cycle Convexity for Graph Products

Autor: Anand, Bijo S., V., Ullas Chandran S., Nascimento, Julliano R., Nair, Revathy S.

Let $G$ be a graph and $S \subseteq V(G)$. In the cycle convexity, we say that $S$ is \textit{cycle convex} if for any $u\in V(G)\setminus S$, the induced subgraph of $S\cup\{u\}$ contains no cycle that includes $u$. The \textit{cycle convex hull} of

Multilingual Mathematical Reasoning: Advancing Open-Source LLMs in Hindi and English

Autor: Anand, Avinash, Prasad, Kritarth, Kirtani, Chhavi, Nair, Ashwin R, Nema, Manvendra Kumar, Jaiswal, Raj, Shah, Rajiv Ratn

Large Language Models (LLMs) excel in linguistic tasks but struggle with mathematical reasoning, particularly in non English languages like Hindi. This research aims to enhance the mathematical reasoning skills of smaller, resource efficient open-sou
