Abstract

We investigate a novel stochastic heat equation driven by a special generalized fractional Gaussian noise. We establish the existence, mixed-self-similarity, and regularity properties of the mild solution. Additionally, we explore the fractal dimensions of the solution sample paths’ graphs and ranges. Our find-ings have potential applications in modeling complex physical phenomena with long-range correlations.
