The Sharp Even-Size Spectral Threshold for $H (4, 3)$ -Free Graphs

Shreyhaan Sarkar

We determine the sharp even-size threshold for the fixed-size spectral extremal problem forbidding $H (4, 3)$ , the graph obtained by identifying one vertex of a $4$ -cycle with one ve…

Visibility cliques, cubic containers, and dense orchard cores

Sohail Sarkar

The Big-Line-Big-Clique Conjecture of Kara, Por and Wood asserts that, for every fixed $k$ and $ℓ$ , every sufficiently large finite planar point set contains either $k$ collinea…
