Discrete octonionic analysis: first ideas and results

Abstract In recent years, there is a growing interest in the studying octonions, which are 8-dimensional hypercomplex numbers forming the biggest normed division algebras over the real numbers. In particular, various tools of the classical complex function theory have been extended to the octonionic setting in recent years. However not so many results related to a discrete octonionic analysis, which is relevant for various applications in quantum mechanics, have been presented so far. Therefore, in this talk, we present first ideas towards discrete octonionic analysis. In particular, we discuss several approaches to a discretisation of octonionic analysis and present several basic tools of discrete octonionic analysis such as the discrete octonionic Stokes’ formulae, Borel-Pompeiu and Cauchy formulae.
