## Abstract The __Γ‘__ βmodulation spaces are a family of spaces that contain the Besov and modulation spaces as special cases. In this paper we prove that brushlet bases can be constructed to form unconditional and even greedy bases for the __Ξ±__ βmodulation spaces. We study __m__ βterm nonlinear a

We prove Kolmogorov's type characterization of best approximation for given \(L \in \mathscr{L}(W, V)\) in finite dimensional subspace \(\mathscr{V} \subset \mathscr{L}(W, V)\). This extends the results obtained by Malbrock for the case \(W=V=c_{0}\) and \(W=C(T), V=C(S)\). co 1995 Academic Press, I
We study certain finite dimensional reproducing kernel indefinite inner product spaces of multiplicative half order differentials on a compact real Riemann surface; these spaces are analogues of the spaces introduced by L. de Branges when the Riemann sphere is replaced by a compact real Riemann surf
