Non-associative gauge theory and higher spin interactions [PDF]

, 2004
We give a framework to describe gauge theory on a certain class of commutative but non-associative fuzzy spaces. Our description is in terms of an Abelian gauge connection valued in the algebra of functions on the cotangent bundle of the fuzzy space. The

Predicting efficacy of 5-fluorouracil therapy via a mathematical model with fuzzy uncertain parameters

Journal of Medical Signals and Sensors, 2022
Background: Due to imprecise/missing data used for parameterization of ordinary differential equations (ODEs), model parameters are uncertain. Uncertainty of parameters has hindered the application of ODEs that require accurate parameters.

The Seiberg-Witten Map on the Fuzzy Sphere [PDF]

, 2003
We construct covariant coordinate transformations on the fuzzy sphere and utilize these to construct a covariant map from a gauge theory on the fuzzy sphere to a gauge theory on the ordinary sphere.

Impacts of entropy generation in second-grade fuzzy hybrid nanofluids on exponentially permeable stretching/shrinking surface

Scientific Reports, 2023
The present investigation aims to use entropy analysis to analyze the unsteady Magnetohydrodynamic (MHD) flow in a second-grade fuzzy hybrid $$\left( {{\text{Al}}_{{2}} {\text{O}}_{{3}} - {\text{Cu/SA}}} \right)$$ Al 2 O 3 - Cu/SA nanofluid over an ...

Review of modern numerical methods for a simple vanilla option pricing problem [PDF]

, 2018
Option pricing is a very attractive issue of financial engineering and optimization. The problem of determining the fair price of an option arises from the assumptions made under a given financial market model.

The Phase Diagram of Scalar Field Theory on the Fuzzy Disc [PDF]

, 2015
Using a recently developed bootstrapping method, we compute the phase diagram of scalar field theory on the fuzzy disc with quartic even potential. We find three distinct phases with second and third order phase transitions between them.

Observer Design for a Class of Nonlinear Descriptor Systems: A Takagi-Sugeno Approach with Unmeasurable Premise Variables

Journal of Control Science and Engineering, 2015
The Takagi-Sugeno (T-S) fuzzy observer for dynamical systems described by ordinary differential equations is widely discussed in the literature.

Uncoding the interdependency of tumor microenvironment and macrophage polarization: insights from a continuous network approach

Frontiers in Immunology, 2023
The balance between pro- and anti-inflammatory immune system responses is crucial to preventing complex diseases like cancer. Macrophages are essential immune cells that contribute to this balance constrained by the local signaling profile of the tumor ...

Topology at the Planck Length [PDF]

, 1997
A basic arbitrariness in the determination of the topology of a manifold at the Planck length is discussed. An explicit example is given of a `smooth' change in topology from the 2-sphere to the 2-torus through a sequence of noncommuting geometries ...

Approximate solutions by artificial neural network of hybrid fuzzy differential equations

Advances in Mechanical Engineering, 2017
In this article, we propose a new approach to solve the hybrid fuzzy differential equations based on the feed-forward neural networks. We first replace it by a system of ordinary differential equations. A trial solution of this system involves two parts.
