Extremal functions for rooted minors
Journal of Graph Theory, 2008AbstractThe graph G contains a graph H as a minor if there exist pairwise disjoint sets {Si ⊆ V(G)|i = 1,…,|V(H)|} such that for every i, G[Si] is a connected subgraph and for every edge uv in H, there exists an edge of G with one end in Su and the other end in Sv. A rooted H minor in G is a minor where each Si of the minor contains a predetermined xi ∈

Extreme distribution functions of copulas
Kybernetika, 2008Summary: We study some properties of the distribution function of the random variable \(C(X,Y)\) when the copula of the random pair \((X,Y)\) is \(M\) (respectively, \(W\)) -- the copula for which each of \(X\) and \(Y\) is almost surely an increasing (respectively, decreasing) function of the other -- and \(C\) is any copula.
