We analytically calculate the topological charge of the noncommutative ADHM U(N) k-instanton using the Corrigan’s identity and find that the result is exactly the instanton number k.
We have calculated the topological charge of U(N) instantons on non-degenerate noncommutative space time to be exactly the instanton number k in a previous paper [1]. This paper, which deals with the degenerate R NC ×R2 case, is the continuation of [1]. We find that the same conclusion holds in this case, thus complete the answer to the problem of topological charge of noncommutative U(N) insta...
The known extended algebras associated with p-branes are shown to be generated as topological charge algebras of the standard pbrane actions. A representation of the charges in terms of superspace forms is constructed. The charges are shown to be the same in standard/extended superspace formulations of the action.
the chromatic number of a graph g, denoted by χ(g), is the minimum number of colors such that g can be colored with these colors in such a way that no two adjacent vertices have the same color. a clique in a graph is a set of mutually adjacent vertices. the maximum size of a clique in a graph g is called the clique number of g. the turán graph tn(k) is a complete k-partite graph whose partition...
Some exact solutions of the (2+1)-dimensional integrable classical continuous isotropic Heisenberg spin chain (the M-XX equation) are obtained by using Hirota's method. These solutions are characterized by an integer topological charge.
The bulk distribution of the topological charge density, constructed via HP 1 σ-model embedding method, is investigated. We show that the existence of quadratic power correction to gluon condensate implies linear divergence of the non-perturbatively defined topological density in the continuum limit. As a consequence, the topologi-cal charge is to be distributed within three-dimensional sign-co...
in this article we study two different generalizations of von neumann regularity, namely strong topological regularity and weak regularity, in the banach algebra context. we show that both are hereditary properties and under certain assumptions, weak regularity implies strong topological regularity. then we consider strong topological regularity of certain concrete algebras. moreover we obtain ...
The chromatic number of a graph G, denoted by χ(G), is the minimum number of colors such that G can be colored with these colors in such a way that no two adjacent vertices have the same color. A clique in a graph is a set of mutually adjacent vertices. The maximum size of a clique in a graph G is called the clique number of G. The Turán graph Tn(k) is a complete k-partite graph whose partition...
