2 00 4 Isomorphic Implication ∗
We study the isomorphic implication problem for Boolean constraints. We show that this is a natural analog of the subgraph isomorphism problem. We prove that, depending on the set of constraints, this problem is in P, NP-complete, or NP-hard, coNP-hard, and in P || . We show how to extend the NP-hardness and coNP-hardness to P || -hardness for some cases, and conjecture that this can be done in...
متن کاملA counterexample to the pseudo 2-factor isomorphic graph conjecture
A graph G is pseudo 2-factor isomorphic if the parity of the number of cycles in a 2-factor is the same for all 2-factors of G. Abreu et al. [1] conjectured that K3,3, the Heawood graph and the Pappus graph are the only essentially 4-edge-connected pseudo 2-factor isomorphic cubic bipartite graphs (Abreu et al., Journal of Combinatorial Theory, Series B, 2008, Conjecture 3.6). Using a computer ...
متن کاملPseudo 2-factor isomorphic regular bipartite graphs
A graph is pseudo 2–factor isomorphic if the numbers of circuits of length congruent to zero modulo four in each of its 2–factors, have the same parity. We prove that there exist no pseudo 2–factor isomorphic
متن کاملUnit 2: Subgroups
In order for this to happen, it must be the case that “ ⋅” is a binary operation on H as well as being a binary operation on G. Recall that when we say that “ ⋅” is a binary operation on G, we mean that “ ⋅” returns an element of G whenever one uses “ ⋅” to combine two elements of G. If “ ⋅” is also going to be an operation on H, this means that if the two input elements a and b come for the su...
متن کاملZariski Dense Subgroups of Semisimple Algebraic Groups with Isomorphic p-adic Closures
We prove under certain natural conditions the finiteness of the number of isomorphism classes of Zariski dense subgroups in semisimple groups with isomorphic p-adic closures.
