Tail and moment estimates for chaoses generated by symmetric random variables with logarithmically concave tails

Adamczak, Radosław · Latała, Rafał

Original · EN

We present two-sided estimates of moments and tails of polynomial chaoses of order at most three generated by independent symmetric random variables with log-concave tails as well as for chaoses of arbitrary order generated by independent symmetric exponential variables. The estimates involve only deterministic quantities and are optimal up to constants depending only on the order of the chaos variable.
