A note on the hypercomplex singular Cauchy-like integral in Douglis analysis

Hypercomplex analysis extends classical complex analysis to Douglis algebras, replacing holomorphic functions with hyperanalytic functions, i.e., null solutions of the Douglis operator in ${\mathbb{R}}^2$ (identifying ${\mathbb{R}}^2$ with $\mathbb{C}$). The hypercomplex singular Cauchy-like integral, is one of the main actors in the hypercomplex analysis and many properties have been studied in recently decades. This paper aims to present local estimates of the hypercomplex singular Cauchy-like integral.
