Tail and moment estimates for some types of chaos

Rafał Latała (1999)

Studia Mathematica

Similarity:

Let $X_{i}$ be a sequence of independent symmetric real random variables with logarithmically concave tails. We consider a variable $X = \sum_{i \neq j} a_{i, j} X_{i} X_{j}$ , where $a_{i, j}$ are real numbers. We derive approximate formulas for the tails and moments of X and of its decoupled version, which are exact up to some universal constants.

Multilinear Calderón-Zygmund operators on Hardy spaces.

Loukas Grafakos, Nigel Kalton (2001)

Collectanea Mathematica

Similarity:

It is shown that multilinear Calderón-Zygmund operators are bounded on products of Hardy spaces.

Orthogonal polynomials and middle Hankel operators on Bergman spaces

Lizhong Peng, Richard Rochberg, Zhijian Wu (1992)

Studia Mathematica

Similarity:

We introduce a sequence of Hankel style operators $H^{k}$ , k = 1,2,3,..., which act on the Bergman space of the unit disk. These operators are intermediate between the classical big and small Hankel operators. We study the boundedness and Schatten-von Neumann properties of the $H^{k}$ and show, among other things, that $H^{k}$ are cut-off at 1/k. Recall that the big Hankel operator is cut-off at 1 and the small Hankel operator at 0.

A variant sharp estimate for multilinear singular integral operators

Guoen Hu, Dachun Yang (2000)

Studia Mathematica

Similarity:

We establish a variant sharp estimate for multilinear singular integral operators. As applications, we obtain the weighted norm inequalities on general weights and certain $L l o g^{+} L$ type estimates for these multilinear operators.

Non-similarity of Walsh and trigonometric systems

P. Wojtaszczyk (2000)

Studia Mathematica

Similarity:

We show that in $L_{p}$ for p ≠ 2 the constants of equivalence between finite initial segments of the Walsh and trigonometric systems have power type growth. We also show that the Riemann ideal norms connected with those systems have power type growth.
