Toroidal Compactification without Vector Structure
Many important ideas about string duality that appear in conventional T compactification have analogs for T compactification without vector structure. We analyze some of these issues and show, in particular, how orientifold planes associated with Sp(n) gauge groups can arise from T -duality and how they can be interpreted in F -theory. We also, in an appendix, resolve a longstanding puzzle conc...
متن کاملExtremal Optimization and Network Community Structure
The network community structure detection problem has been recently approached with several variants of an extremal optimization algorithm. An extremal optimization algorithm is a stochastic local search method that evolves pairs of individuals that can be represented as having several components by randomly replacing components having worst fitnesses. The number of components to be replaced in...
متن کاملBicompletion and Samuel Bicompactification
It is proved that the quasi-proximity space induced by the bicompletion of a quasi-uniform T0-space X is a subspace of the quasi-proximity space induced by the Samuel bicompactification of X. The result is then used to establish that the locally finite covering quasi-uniformity defined on the category Top0 of topological T0-spaces and continuous maps is not lower K-true (in the sense of Brümmer...

We describe a broad program of research in parameterized complexity, and hows this plays out for the M AX LEAF SPANNING TREE problem.
متن کاملEccentric Connectivity Index: Extremal Graphs and Values
Eccentric connectivity index has been found to have a low degeneracy and hence a significant potential of predicting biological activity of certain classes of chemical compounds. We present here explicit formulas for eccentric connectivity index of various families of graphs. We also show that the eccentric connectivity index grows at most polynomially with the number of vertices and determine ...
