On topological charge indices of graphs

2023
Summary: We introduce a fast method of computing the topological charge indices of simple graphs (molecules) which does not require matrices of large sizes. For the case of trees, we give a compact formula and in the general case we obtain upper and lower bounds for the charge indices.

Charges and Topology

Nuclear Physics B - Proceedings Supplements, 2007
The extent to which we can construct electric, coloured and magnetic charges in gauge theories will be discussed. The global properties of the charged sectors will be touched upon and through this its relation to confinement and infrared dynamics.

On topological excitations with isovector topological charges

Journal of Experimental and Theoretical Physics Letters, 1996
It is shown that degenerate systems with order parameter ψ taking on values in compact homogeneous subspaces TG or G/TG (where G is a simple compact group and TG is its maximum commutative subgroup) possess a rich collection of topological excitations (vortices or, correspondingly, instantons) with isovector topological charges.
