An induced subgraph S of a graph G is called a derived subgraph of G if S contains no isolated vertices. An edge e of G is said to be residual if e occurs in more than half of the derived subgraphs of G. We introduce the conjecture: Every non-empty graph contains a non-residual edge. This conjecture

A well-known conjecture of Broue in the representation theory of finite groups Γnvolves equivalences of derived categories of blocks. The aim of this paper is to verify this conjecture for defect 2 blocks of symmetric groups. Actually we prove for these blocks a refinement of Broue's conjecture due
The quality of the results obtained in calculations with the hybrid QM/MM method IMOMM on systems where the heme group is partitioned in QM and MM regions is evaluated through the performance of calculations on the 4-coordinate [Fe(P)] (P = porphyrin), the 5-coordinate [Fe(P)(1 -(Me)Im)] (Im = imida
