报告摘要:I will present three instances of the intersection of Enumerative Combinatorics with Coding Theory, Mathematical Biology, and Number Theory: Constrained Coding Bounds via Goulden–Jackson Cluster Theorem. Proof of a conjecture on tree-child networks proposed by Pons and Batle via Young tableaux with walls. Arithmetic of tangent numbers and binomial-secant numbers via combinatorial identities and the Kummer $p$-adic Theorem.
