Kochubei A.N. p-ADIC COMMUTATION RELATIONS (12K, AMS-TeX) ABSTRACT. Representations of the canonical and deformed commutation relations by bounded operators on $p$-adic Banach spaces are constructed. Functions from the Mahler basis of the space of $p$-adic continuous functions and their multiplicative analogues are shown to be the $p$-adic counterparts of the Hermite and $q$-Hermite functions. The analogue of the Stone-von Neumann uniqueness theorem fails in the $p$-adic case.
