Topological properties of convolutor spaces via the short-time Fourier transform

Key words: Mulholland inequality, Hilbert-type inequality, weight function, equiv- alent form, the best possible constant factor.. The above inequality includes the best

We recall there are three classical definitions of the topological dimension : the small inductive dimension, denoted by ind, the large inductive dimension, denoted

In this paper with a further modification of Artin’s defi- nition of n-polygon we will prove the following property: let X be a topological space with finitely

In w we reformulate the Main Theorem, discuss the analogies with our previous paper [5], and derive an important corollary describing all closed right

Together with classical Fourier theory these results constitute a unified Fourier analysis on RSS related to, but distinct from the established alternatives of

Usually there is no w a y of controlling the topological respectability of sets obtained b y use of the axiom of choice, and quite different methods have to

The theory of spaces with negative curvature began with Hadamard's famous paper [9]. This condition has a meaning in any metric space in which the geodesic

But for finite depth foliations (which have two sided branching), there are many examples where it is impossible to make the pseudo-Anosov flow transverse to the foliation [Mo5] and
