We investigate gravitational lensing by \textit{special} Buchdahl inspired
metric with the Buchdahl parameter . In strong deflection limit, we
derive the deflection angle analytically for the light rays that diverge as
photons ap...

Large Language Models (LLMs) exhibit great potential in complex multi-step
reasoning through inference-time thinking but still struggle with deciding when
to stop thinking due to limited self-awareness about their knowledge
boundaries. Whil...
