Weak Hopf algebra structures on hybrid numbers

Abstract

Let $\mathbb{K}$ be the set of hybrid numbers. This paper is to look for all the weak Hopf structures on $\mathbb{K}$. Once $\mathbb{K}$ is endowed with a structure of a weak Hopf algebra, we shall compute the source algebra and target algebra of $\mathbb{K}$. Also, we shall discuss the integrals in such weak Hopf algebra $\mathbb{K}$.
