TT¯ -deformed actions and (1,1) supersymmetry
(Springer, 2019-10)
We describe an algorithmic method to calculate the TT¯ deformed Lagrangian of a given seed theory by solving an algebraic system of equations. This method is derived from the topological gravity formulation of the deformation. ...
T-duality on nilmanifolds
(Springer, 2018-05)
We study generalized complex structures and T-duality (in the sense of Bouwknegt, Evslin, Hannabuss and Mathai) on Lie algebras and construct the corresponding Cavalcanti and Gualtieri map. Such a construction is called ...
Computing Tutte polynomials of contact networks in classrooms
(SPIE-INT SOC OPTICAL ENGINEERING, 2013-01-01)
Objective: The topological complexity of contact networks in classrooms and the potential transmission of an infectious disease were analyzed by sex and age. Methods: The Tutte polynomials, some topological properties and ...
Two examples of vanishing and squeezing in K1
(State University of New York, 2020-06)
Controlled topology is one of the main tools for proving the isomorphism conjecture concerning the algebraic K-theory of group rings. In this article we dive into this machinery in two examples: when the group is infinite ...
The homotopy types of the posets of p-subgroups of a finite group
(Academic Press Inc Elsevier Science, 2018-04)
We study the homotopy properties of the posets of p-subgroups Sp(G) and Ap(G) of a finite group G, viewed as finite topological spaces. We answer a question raised by R.E. Stong in 1984 about the relationship between the ...

Abductive Spaces: Modeling Concept Framework Revision with Category Theory
(Springer, 2021)
A formal model of abductive inference is provided in which abduction is conceived as expansive and contractive movements through a topological space of theoretical and practical commitments. A pair of presheaves over the ...
Tutte polynomials and topological quantum algorithms in social network analysis for epidemiology, bio-surveillance and bio-security
(SPRINGER, 2008-01-01)
The Tutte polynomial and the Aharonov-Arab-Ebal-Landau algorithm are applied to Social Network Analysis (SNA) for Epidemiology, Biosurveillance and Biosecurity. We use the methods of Algebraic Computational SNA and of ...
