Generalization of Navascués' α-fractal operator on lifted Sierpiński gasket
Abstract
The primary objective of the present article is to extend Navascués' class of α-fractal interpolation functions (α-FIFs) from a Euclidean domain to a non-Euclidean domain. Precisely, we consider the lifted Sierpiński gasket (SG̃), which is a subset of the first Heisenberg group equipped with a \textit{non-Euclidean metric} (popularly known as the Heisenberg metric), and demonstrate the existence of the class of α-FIFs in the continuous space on SG̃. Subsequently, we derive certain conditions on the parameters so that the same class lies in the Hölder space on SG̃. Next, we extend the theory of Navascués' α-fractal operator from the Euclidean space to the Heisenberg space, and we also report several properties of the same operator. Additionally, we discuss certain dimensional results of the graphs of the functions with respect to the Heisenberg metric besides the Euclidean metric. We also cover some of the dimensional preserving and the set-valued results corresponding to the dimension of the graphs of the functions.
