On Onesided Harmonic Analysis [PDF]
Proceedings of the American Mathematical Society, 1980 It is shown that, in locally compact groups satisfying the onesided version of the Wiener property introduced by Leptin, characters of closed subgroups have always continuous positive definite extensions onto the whole group. We give a quick proof that for such groups the connected component of the identity is the direct product of a compact group and ...

On some aspects of the dynamic behavior of the softening Duffing oscillator under harmonic excitation [PDF]
, 2016 The Duffing oscillator is probably the most popular example of a nonlinear oscillator in dynamics. Considering the case of softening Duffing oscillator with weak damping and harmonic excitation and performing standard methods like harmonic balance or ...

Adaptive Harmonic Analysis [PDF]
, 1991 In this paper we describe a new approach to the harmonic analysis of the tide. For a number of reasons the harmonic constants are not really constant but vary slowly in time.

Harmonic Analysis in One-Parameter Metabelian Nilmanifolds [PDF]
, 2011 Let $G$ be a connected, simply connected one-parameter metabelian nilpotent Lie group, that means, the corresponding Lie algebra has a one-codimensional abelian subalgebra. In this article we show that $G$ contains a discrete cocompact subgroup.

The orthosymplectic Lie supergroup in harmonic analysis [PDF]
, 2010 The study of harmonic analysis in superspace led to the Howe dual pair (O(m) x Sp(2n); sl2). This Howe dual pair is incomplete, which has several implications. These problems can be solved by introducing the orthosymplectic Lie supergroup OSp(m|2n).

Harmonic analysis on the infinite symmetric group [PDF]
, 2003 Let S be the group of finite permutations of the naturals 1,2,... The subject of the paper is harmonic analysis for the Gelfand pair (G,K), where G stands for the product of two copies of S while K is the diagonal subgroup in G.

On an atomic decomposition in Banach spaces [PDF]
Sahand Communications in Mathematical Analysis, 2018 An atomic decomposition is considered in Banach space. A method for constructing an atomic decomposition of Banach space, starting with atomic decomposition of subspaces is presented. Some relations between them are established.
