THE β-FUNCTION IN TOPOLOGICAL SIGMA MODELS

Modern Physics Letters A, 1991
The one-loop β-function is computed for topological sigma models. By gauge fixing the topological shift symmetry in the delta-function gauge, we find that the theory is finite with vanishing β-function. A similar result is shown to hold for supersymmetric quantum mechanics.

CORRELATION FUNCTIONS FOR TOPOLOGICAL LANDAU-GINZBURG MODELS WITH c≤3

International Journal of Modern Physics A, 1992
We discuss c≤3 topological Landau-Ginzburg models. In particular we give the potential for the three exceptional models E6,7,8 in the constant metric coordinates of coupling constant space and derive the generating function F for correlation functions.

Topological modeling of brain functioning

2017 E-Health and Bioengineering Conference (EHB), 2017
in this paper, topological parameters are considered, since topology gives the initial meaning to the structure of networks. A technique is proposed that allows determining the key topological characteristics of networks and giving them quantitative and qualitative estimates. To determine the direction of development of structures, a principle has been

Topological Functioning Model as a CIM-Business Model

2011
The first model in Model Driven Architecture (MDA) is a Computation Independent Model (CIM) that specifies domain information. One of issues discussed in this chapter is the meaning of “computation independence”. Another one is formalism of CIMs. And the last issue discussed is a use of a Topological Functioning Model (TMF) for problem domain modeling ...

New topological aspects of fermionic correlation functions in the Schwinger model

Physical Review D, 1990
We perform the path-integral bosonization of the Schwinger model in a topologically nontrivial sector. We show the existence of certain fermionic correlation functions which, being zero if only the trivial topological sector is considered, develop nonzero values due to the presence of the topological configuration.
