Jumping spectra and vanishing couplings in heterotic Line Bundle Standard Models

Journal of High Energy Physics, 2019
We study two aspects of the physics of heterotic Line Bundle Standard Models on smooth Calabi-Yau threefolds. First, we investigate to what degree modern moduli stabilization scenarios can affect the standard model spectrum in such compactifications ...

Generalized Sums over Histories for Quantum Gravity I. Smooth Conifolds [PDF]

, 1993
This paper proposes to generalize the histories included in Euclidean functional integrals from manifolds to a more general set of compact topological spaces.

Classification of Cipher Text by Clustering of S-Topological Rough Group

IEEE Access
Rough set theory provides valuable tools for handling and analyzing ciphertext, making it a prominent asset in cryptographic applications. Its ability to manage uncertainty and reduce complexity can enhance various aspects of ciphertext management, from ...

Aspects of the topological dynamics of sparse graph automorphism groups

, 2021
We examine sparse graph automorphism groups from the perspective of the Kechris-Pestov-Todor evi (KPT) correspondence. The sparse graphs that we discuss are Hrushovski constructions: we consider the 'ab initio Hrushovski construction M_0, the Fra ss limit of the class of 2-sparse graphs with self-sufficient closure; M_1, a simplified version ...

Holonomy and monodromy groupoids [PDF]

, 2001
We outline the construction of the holonomy groupoid of a locally Lie groupoid and the monodromy groupoid of a Lie groupoid. These specialise to the well known holonomy and monodromy groupoids of a foliation, when the groupoid is just an equivalence ...

Non-Abelian Monopoles on Four-Manifolds [PDF]

, 1995
We present a non-abelian generalization of Witten monopole equations and we analyze the associated moduli problem, which can be regarded as a generalization of Donaldson theory.

An Algebraic Approach of Topological Indices Connected with Finite Quasigroups

Journal of Function Spaces
In mathematical chemistry, the algebraic polynomial serves as essential for calculating the most accurate expressions of distance-based, degree-distance-based, and degree-based topological indices.

Generalized Sums over Histories for Quantum Gravity II. Simplicial Conifolds

, 1993
This paper examines the issues involved with concretely implementing a sum over conifolds in the formulation of Euclidean sums over histories for gravity.

Topological Classification of Limit Cycles of Piecewise Smooth Dynamical Systems and Its Associated Non-Standard Bifurcations

Entropy, 2014
In this paper, we propose a novel strategy for the synthesis and the classification of nonsmooth limit cycles and its bifurcations (named Non-Standard Bifurcations or Discontinuity Induced Bifurcations or DIBs) in n-dimensional piecewise-smooth dynamical
