WSEAS Transactions on Mathematics, 2020 The paper describes the results of a functional-geometric study of the necessary and sufficient conditions for the existence of a differential realization in the terms of the tensor product of real Hilbert spaces. There are considered continuous infinite-

Twisted string theory in anti-de Sitter space
Journal of High Energy Physics, 2020 We construct a string theory in three-dimensional anti-de Sitter space-time that is independent of the boundary metric. It is a topologically twisted theory of quantum gravity. We study string theories with an asymptotic N = 2 superconformal symmetry and

BPS skyrmions of generalized Skyrme model in higher dimensions
Journal of High Energy Physics, 2022 In this work we consider the higher dimensional Skyrme model, with spatial dimension d > 3, focusing on its BPS submodels and their corresponding features.

On the joint continuity of module multiplication [PDF]
Proceedings of the Estonian Academy of Sciences, 2023 Let A be any topological algebra over R or C. We show that the property of a topological left (right or two-sided) A-module to have a jointly continuous action of A is inherited by submodules, quotient modules, completion, direct products, direct sums ...

Topologies on quotient space of matrices via semi‐tensor product [PDF]
Asian journal of control, 2018 An equivalence of matrices via semi‐tensor product (STP) is proposed. Using this equivalence, the quotient space is obtained. Parallel and sequential arrangements of the natural projection on different shapes of matrices lead to the product topology and ...

Perturbative 4D conformal field theories and representation theory of diagram algebras
Journal of High Energy Physics, 2020 The correlators of free four dimensional conformal field theories (CFT4) have been shown to be given by amplitudes in two-dimensional so(4, 2) equivariant topological field theories (TFT2), by using a vertex operator formalism for the correlators.

Topological vacuum structure of the Schwinger model with matrix product states [PDF]
Physical Review D, 2019 We numerically study the single-flavor Schwinger model with a topological $\theta$-term, which is practically inaccessible by standard lattice Monte Carlo simulations due to the sign problem.

Non-onsite symmetries and quantum teleportation in split-index matrix product states [PDF]
QuantumWe describe a class of spin chains with new physical and computational properties. On the physical side, the spin chains give examples of symmetry-protected topological phases that are defined by non-onsite symmetries, i.e., symmetries that are not a ...
