Abstract:

Knot invariants can be defined using algebraic structures whose axioms encode the Reidemeister moves via sets of homomorphisms known as homsets. The homset invariant can be further enhanced with additional structure to obtain stronger invariants by adapting other knot invariants to the case of homset elements interpreted as colored knot diagrams. In this talk we will see some recent examples of these invariants known as Biquandle Brackets, a family of invariants which include classical skein invariants like the Alexander-Conway and Jones-Kauffman polynomials as well as quandle and biquandle 2-cocycle invariants and more.

An Approximate Analytic Solution for the Multidimensional Fractional-Order Time and Space Burger Equation Based on Caputo-Katugampola Derivative

An Approximate Analytic Solution for the Multidimensional Fractional-Order Time and Space Burger Equation Based on Caputo-Katugampola Derivative Wannika Sawangtong, Akpan N. Ikot, Panumart Sawangtong The (n+1)-dimensional space and time fractional-order Burger equation with Caputo-Katugampola derivative is tackled using the generalized Laplace homotopy perturbation procedure (GLHPM) to derive an approximate analytic solution. The coefficients of this

An Analysis of the Fractional-Order Option Pricing Problemvfor Two Assets by the Generalized Laplace Variational Iteration Approach

An Analysis of the Fractional-Order Option Pricing Problemvfor Two Assets by the Generalized Laplace Variational Iteration Approach Sivaporn Ampun, Panumart Sawangtong, and Wannika Sawangtong The Black–Scholes equation is a fundamental model in option pricing theory. This manuscript introduces a novel approach by formulating the classical Black–Scholes equation as a fractional-order equation using the generalized Riemann–Liouville
