NONCOMMUTATIVE GAUGE THEORIES: MODEL FOR HODGE THEORY [PDF]

open access: yesInternational Journal of Modern Physics A, 2013
The nilpotent Becchi–Rouet–Stora–Tyutin (BRST), anti-BRST, dual-BRST and anti-dual-BRST symmetry transformations are constructed in the context of noncommutative (NC) 1-form as well as 2-form gauge theories. The corresponding Noether's charges for these symmetries on the Moyal plane are shown to satisfy the same algebra, as by the de Rham ...

A matrix model from string field theory

open access: yesFrontiers in Physics, 2016
We demonstrate that a Hermitian matrix model can be derived from level truncated open string field theory with Chan-Paton factors. The Hermitian matrix is coupled with a scalar and U(N) vectors which are responsible for the D-brane at the tachyon vacuum.

Applying Set Theory

open access: yesAxioms, 2021
We prove some results in set theory as applied to general topology and model theory. In particular, we study ℵ1-collectionwise Hausdorff, Chang Conjecture for logics with Malitz-Magidor quantifiers and monadic logic of the real line by odd/even Cantor ...

The Axiomatic Approach to Non-Classical Model Theory

open access: yesMathematics, 2022
Institution theory represents the fully axiomatic approach to model theory in which all components of logical systems are treated fully abstractly by reliance on category theory. Here, we survey some developments over the last decade or so concerning the

A Model-Invariant Theory of Causation [PDF]

open access: yes, 2021
I provide a theory of causation within the causal modeling framework. In contrast to most of its predecessors, this theory is model-invariant in the following sense: if the theory says that C caused (didn't cause) E in a causal model, M, then it will ...

Algebras of Binary Isolating Formulas for Tensor Product Theories

open access: yesИзвестия Иркутского государственного университета: Серия "Математика", 2022
Algebras of distributions of binary isolating and semi-isolating formulae are derived objects for a given theory and reflect binary formula relations between 1-type realizations.

Black Holes and Complexity via Constructible Universe

open access: yesUniverse, 2020
The relation of randomness and classical algorithmic computational complexity is a vast and deep subject by itself. However, already, 1-randomness sequences call for quantum mechanics in their realization.

Algebras of Binary Isolating Formulas for Strong Product Theories

open access: yesИзвестия Иркутского государственного университета: Серия "Математика", 2023
Algebras of distributions of binary isolating and semi-isolating formulas are objects that are derived for a given theory, and they specify the relations between binary formulas of the theory.

Model-Based Systems Engineering Applied to Trade-Off Analysis of Wireless Power Transfer Technologies for Implanted Biomedical Microdevices

open access: yesSensors, 2021
Decision-making is an important part of human life and particularly in any engineering process related to a complex product. New sensors and actuators based on MEMS technologies are increasingly complex and quickly evolving into products.
