$L_{\infty}$ -Khintchine-Bonami inequality in free probability

Artur Buchholz (1998)

Banach Center Publications

Similarity:

We prove the norm estimates for operator-valued functions on free groups supported on the words with fixed length ( $f = \sum_{| w | = l} a_{w} \otimes λ (w)$ ). Next, we replace the translations by the free generators with a free family of operators and prove inequalities of the same type.

Free spaces

Similarity:

A space Y is called a free space if for each compactum X the set of maps with hereditarily indecomposable fibers is a dense $G_{δ}$ -subset of C(X,Y), the space of all continuous functions of X to Y. Levin proved that the interval I and the real line ℝ are free. Krasinkiewicz independently proved that each n-dimensional manifold M (n ≥ 1) is free and the product of any space with a free space is free. He also raised a number of questions about the extent of the class of free spaces. In this...

Existence of local solutions for free boundary problems for viscous compressible barotropic fluids

W. M. Zajączkowski (1995)

Annales Polonici Mathematici

Similarity:

We prove the local existence of solutions for equations of motion of a viscous compressible barotropic fluid in a domain bounded by a free surface. The solutions are shown to exist in exactly those function spaces where global solutions were found in our previous papers [14, 15].

On a problem of Steve Kalikow

Saharon Shelah (2000)

Fundamenta Mathematicae

Similarity:

The Kalikow problem for a pair (λ,κ) of cardinal numbers,λ > κ (in particular κ = 2) is whether we can map the family of ω-sequences from λ to the family of ω-sequences from κ in a very continuous manner. Namely, we demand that for η,ν ∈ ω we have: η, ν are almost equal if and only if their images are. We show consistency of the negative answer, e.g., for $ℵ_{ω}$ but we prove it for smaller cardinals. We indicate a close connection with the free subset property and its variants. ...
