Hong Liu, A proof of Mader’s conjecture on large clique subdivisions in $C_4$-free graphs
Room 1401, Bldg. E6-1, KAISTGiven any integers $s,t\geq 2$, we show there exists some $c=c(s,t)>0$ such that any $K_{s,t}$-free graph with average degree $d$ contains a subdivision of a clique with at least $cd^{\frac{1}{2}\frac{s}{s-1}}$ …
