Generalized fractional Brownian motion (1704.02103v1)

Abstract: We introduce a new Gaussian process, a generalization of both fractional and subfractional Brownian motions, which could serve as a good model for a larger class of natural phenomena. We study its main stochastic properties and some increments characteristics. As an application, we deduce the properties of nonsemimartingality, H\"{o}lder continuity, nondifferentiablity, and existence of a local time.
