Abstract

The main result of this contribution is the derivation of the exact asymptotic behavior of the supremum of a class of α ( t ) \alpha (\mathbf {t}) -locally stationary Gaussian random fields. We present two applications of our result: the first one deals with the extremes of aggregate multifractional Brownian motions, whereas the second one establishes the exact asymptotics of the supremum of the χ \chi -process generated by multifractional Brownian motions.
