... way that may permit analysis of the latter (for example, the matrix powers of A enumerate walks on G – see below). The homomorphism G-profile of G, an infinite sequence of natural numbers, may also seem to be too unwieldy a graph invariant to be useful (even allowing that for given G it is possible ...

GALOIS THEORY
... has a non-trivial solution if the number of unknowns exceeds the number of equations. The proof of this follows the method familiar to most high school students, namely, successive elimination of unknowns. If no equations in n > 0 variables are prescribed, then our unknowns are unrestricted and we m ...

Strong isomorphism reductions in complexity theory
... Recall that the partial ordering of an atomless Boolean algebra has infinite antichains and infinite chains, even chains of ordertype the rationals. Remark 4.2 By the preceding result, for example we see that there exist an infinite ≤iso -antichain of classes C below Lop, whose problems Iso(C) are p ...
