چکیده
We introduce almost diagonal matrices in the setting of (anisotropic) discrete homogeneous Triebel-Lizorkin type spaces and modulation spaces, it is shown that class closed under matrix multiplication. then connect results to continuous show “change frame” for a pair time-frequency frames, with suitable decay properties, diagonal. As an application this result, we consider construction compactly supported frame expansions decomposition associated spaces.

متن کاملRegularity of the Fourier transform on spaces of homogeneous distributions
1. Introduction. In this paper we consider the action of the Fourier transform on spaces of regular homogeneous distributions on R n , by which we mean to include the nonisotropic (sometimes called quasihomogeneous [6]) case. Specifically , consider the group of dilations of R n with positive scaling exponents dn x n) for δ > 0 (we will write this map as δ • x for short). Dilation induces scali...
متن کاملA remark on Remainders of homogeneous spaces in some compactifications
We prove that a remainder $Y$ of a non-locally compact rectifiable space $X$ is locally a $p$-space if and only if either $X$ is a Lindel"{o}f $p$-space or $X$ is $sigma$-compact, which improves two results by Arhangel'skii. We also show that if a non-locally compact rectifiable space $X$ that is locally paracompact has a remainder $Y$ which has locally a $G_{delta}$-diagonal, then...
متن کاملA Class of compact operators on homogeneous spaces
Let $varpi$ be a representation of the homogeneous space $G/H$, where $G$ be a locally compact group and $H$ be a compact subgroup of $G$. For an admissible wavelet $zeta$ for $varpi$ and $psi in L^p(G/H), 1leq p <infty$, we determine a class of bounded compact operators which are related to continuous wavelet transforms on homogeneous spaces and they are called localization operators.
متن کاملEmpirical Localization of Homogeneous Divergences on Discrete Sample Spaces
In this paper, we propose a novel parameter estimator for probabilistic models on discrete space. The proposed estimator is derived from minimization of homogeneous divergence and can be constructed without calculation of the normalization constant, which is frequently infeasible for models in the discrete space. We investigate statistical properties of the proposed estimator such as consistenc...
