Résumé: In this article a class of multifractional processes is introduced, called generalized multifractional gaussian processes (GPMP). For such multifractional models, the hurst exponent of the celebrated fractional brownian motion is replaced by a function, called the multifractional function, which may be irregular. The main aim of this paper is to show how to identify irregular multifractional functions are also given.
