The Language of Self-Suppressiony element . of . we associate a permutation (also denoted .) of ., such that for all . ∈ . and ., . ∈ . we have . Thus an action of . on . is the same as a homomorphism ., where . denotes the symmetric group of all permutations of ..

If any of the prisoners does not see his or her own name, then they are all killed. The prisoners may have a discussion before the first prisoner enters the room with the boxes, but afte

Ian Varcoe,Maureen McNeil,Steven YearleyThe Matrix-Tree Theorem is a formula for the number of spanning trees of a graph in terms of the determinant of a certain matrix. We begin with the necessary graph-theoretical background. Let . be a finite graph, allowing multiple edges but not loops. (Loops could be allowed, but they turn out to be completely irrelevant.)
