in this paper we introduce the notions of uniformly quasi-primary ideals and uniformly classical quasi-primary submodules that generalize the concepts of uniformly primary ideals and uniformly classical primary submodules; respectively. several characterizations of classical quasi-primary and uniformly classical quasi-primary submodules are given. then we investigate for a ring $r$, when any fi...

We consider quasi-periodically systems in the presence of dissipation and study existence response solutions, i.e. quasi-periodic solutions with same frequency vector as forcing term. When is large enough a suitable function involving has simple zero, are known to exist without assuming any non-resonance condition on vector. analyse case non-simple zeroes and, order deal small divisors, we conf...

Setting of this paper is Bishop's constructive mathematics. For a relation σ on a set with apartness is called quasi-antiorder if it is consistent and cotransitive. The quasi-antiorder σ is complete if holds . 0 1 / = σ σ − ∩ In this paper the following assertion ‘A quasi-antiorder is the intersection of a collection of quasi-antiorders.’ is given.

In this paper we generalize the absolute bound for association schemes to coherent configurations. We examine this bound in the context of quasi-symmetric and strongly regular designs. In particular, we use it to derive a new feasibility condition for strongly regular designs and give examples of parameter sets ruled out by this condition but which pass all other feasibility conditions known to...

Several density-matrix renormalization group methods have been proposed to compute the momentumand frequency-resolved dynamical correlation functions of low-dimensional strongly correlated systems. The most relevant approaches are discussed in this contribution. Their applications in various studies of quasi-one-dimensional strongly correlated systems (spin chains, itinerant electron systems, e...

The high strain rate behavior of two cellular materials was investigated using a quasi-static loading stage and a Kolsky bar apparatus. The yield stress of these core materials under dynamic loading was found higher than in quasi-static loading. However, the plateau stress after yielding is not so sensitive to strain rate. For Aluminum foam materials, the deformation was more localized for quas...
