On classification of measurable functions of several variables
A. M. Vershik St. Petersburg Department of V. A. Steklov Institute of Mathematics, Russian Academy of Sciences, St. Petersburg, Russia
Abstract:
We define a normal form (called the canonical image) of an arbitrary measurable function of several variables with respect to a natural group of transformations, describe a new complete system of its invariants (the system of joint distributions), and relate these notions to matrix distributions, i.e., another invariant of measurable functions, which was found earlier and is a random matrix.
Key words and phrases:
classification of functions, matrix distribution, canonical form, joint distributions.
