We propose to detect isomorphisms of algebraic modular speci cations, by representing speci cations as diagrams over a category C0 of base speci cations and speci cation morphisms. We start with a formulation of modular speci cations as terms, which are interpreted as diagrams. This representation has the advantage of being more abstract, i.e. less dependent of one speci c construction than ter...

We extend some results of Rosenthal, Cembranos, Freniche, E. Saab-P. Saab and Ryan to study the geometry of copies and complemented copies of c0(Γ) in the classical Banach spaces C(K,X) in terms of the cardinality of the set Γ, of the density and caliber of K and of the geometry of X and its dual space X∗. Here are two sample consequences of our results: (1) If C([0, 1], X) contains a copy of c...

in this paper we consider c0-group of unitary operators on a hilbert c*-module e. in particular we show that if a?l(e) be a c*-algebra including k(e) and ?t a c0-group of *-automorphisms on a, such that there is x?e with =1 and ?t (?x,x) = ?x,x t?r, then there is a c0-group ut of unitaries in l(e) such that ?t(a) = ut a ut*.

A segment-based C0 (the zero-th order of cepstral coefficient) adaptation scheme for PMC-based Mandarin speech recognition is proposed in this paper. It incorporates a new C0 model of speech signal into the PMC method to improve the gain matching between the clean-speech HMM models and the current noise model. The C0 model is constructed in the training phase by jointly modeling the normalized ...

The space c0 lies at the heart of many constructions of higher order smooth functions on Banach spaces. To name a few, recall Torunczyk’s proof of the existence of C-smooth partitions of unity on WCG spaces ([12]) or Haydon’s recent constructions of C-bump functions on certain C(K) spaces ([7]). The crucial property of c0 that allows for those constructions is a rich supply of C -smooth functio...

We study conformal quantities at generic parameters with respect to the harmonic measure on boundary of connectedness loci Md for unicritical polynomials fc(z)=zd+c. It is known that these are structurally unstable and have stochastic dynamics. prove C1+α2d+α−ϵ-conformality, α=2−HD(Jc0), parameter-phase space similarity maps ϒc0(z):C↦C typical c0∈∂Md establish globally quasiconformal ϒc0(z), c0...
