• Debsoumya Chakraborti, Maximum number of cliques in a graph with bounded maximum degree

    Room B232 IBS (기초과학연구원)

    Generalized extremal problems have been one of the central topics of study in extremal combinatorics throughout the last few decades. One such simple-looking problem, maximizing the number of cliques of a fixed order in a graph with a fixed number of vertices and given maximum degree, was recently resolved by Chase. Settling a conjecture of

  • Debsoumya Chakraborti, Rainbow matchings in edge-colored simple graphs

    Room B232 IBS (기초과학연구원)

    There has been much research on finding a large rainbow matching in a properly edge-colored graph, where a proper edge coloring is a coloring of the edge set such that no same-colored edges are incident. Barát, Gyárfás, and Sárközy conjectured that in every proper edge coloring of a multigraph (with parallel edges allowed, but not

  • Debsoumya Chakraborti, Some classical problems in graph saturation

    Room B232 IBS (기초과학연구원)

    Graph saturation is one of the oldest areas of investigation in extremal combinatorics. A graph $G$ is called $F$-saturated if $G$ does not contain a subgraph isomorphic to $F$, but the addition of any edge creates a copy of $F$. The function $\operatorname{sat}(n,F)$ is defined to be the minimum number of edges in an $n$-vertex
