Orthogonal Polynomials with Recursion Coefficients of Generalized Bounded Variation
n=0 |eiφlβ n+1 − β n | <∞ for some φl ∈ R. This includes discrete Schrödinger operators on a half-line or line with finite linear combinations of Wigner–von Neumann potentials cos(nφ+α)/n , where γ > 0. For the real line, our results state that in the Lebesgue decomposition dμ = fdm+ dμs of such measures, supp(dμs) ∩ (−2, 2) is contained in an explicite finite set S (thus, dμ has no singular co...
متن کاملSome Remarks on Generalized Sequence Space of Bounded Variation of Sequences of Fuzzy Numbers
The idea of difference sequences of real (or complex) numbers was introducedby Ki zmaz cite{Kizmaz}. In this paper, using the difference operator and alacunary sequence, we introduce and examine the class of sequence $bv_{theta}left( Delta,mathcal{F}right) .$ We study some of its properties likesolidity, symmetricity, etc.
متن کاملA Note on Fourier Coefficients of Poincaré Series
We give a short and “soft” proof of the asymptotic orthogonality of Fourier coefficients of Poincaré series for classical modular forms as well as for Siegel cusp forms, in a qualitative form.
متن کاملA Note on Artinianess of Certain Generalized
Let ?: R0?R be a ring homomorphism and suppose that a and a0, respectively, are ideals of R and R0 such that is an Artinian ring. Let M and N be two finitely generated R-modules and suppose that (R0,m0) is a local ring. In this note we prove that the R-modules and are Artinian for all integers i and j, whenever and . Also we will show that if a is principal, then the R-modules and ...
متن کاملA Novel Generalized Topology for Multi-level Inverter with Switched Series-parallel DC Sources (RESEARCH NOTE)
This paper presents a novel topology of single-phase multilevel inverter for low and high power applications. It consists of polarity (Level) generation circuit and H Bridge. The proposed topology can produce higher output voltage levels by connecting dc voltage sources in series and parallel. The proposed topology utilizes minimum number of power electronic devices which helps in reduction o...
