摘要:A Banach space X has Pełczyński’s property (V) if for every Banach space Y every unconditionally converging operator T : X → Y is weakly compact. H.Pfitzner proved that C *-algebras have Pełczyński’s property (V). In the preprint (Krulišová, (2015)) the author ex...

摘要:We obtain upper and lower bounds for the nonlinear variational capacity of thin annuli in weighted \(\mathbf {R}^n\) and in metric spaces, primarily under the assumptions of an annular decay property and a Poincaré inequality. In particular, if the measure has the 1-annular...

摘要:... In this paper, the relaxation test is used to study variation in the time-dependent property of rock and the consequent effect on time-dependent roof failure. This investigation uses a numerical simulation in 3DEC. The relaxation equation is developed from Burgers model. Vari...

摘要:The first goal of this note is to study the Almansi property on an m -dimensional model in the sense of Greene and Wu and, more generally, in a Riemannian geometric setting. In particular, we shall prove that the only model on which the Almansi property is verified is the Eucli...

摘要:A Banach space operator satisfies property ( b ) if the complement of its essential Weyl approximate point spectrum in its approximate point spectrum is the set of all poles of the resolvent of finite rank. Property ( b ) does not transfer from operators A and B to their tensor p...

摘要:... We show that relevant combinatorial properties (such as the amalgamation property, Ramsey property and ordering property) carry over from a category to an equivalent category. We then use these results to show that the category whose objects are isomorphic copies of finite p...

摘要:... Next, by establishing the model of mine pillar with one inclined shear-band and by simplifying the stress evolution on the band, based on the necessary physical characteristics for triggering dynamic events, the basic mechanical property of mine pillar required for trigge...

摘要:We study Property (T) for locally compact quantum groups, providing several new characterisations, especially related to operator algebraic ergodic theory. Quantum Property (T) is described in terms of the existence of various Kazhdan type pairs, and some earlier structural re...

摘要:... The effect of rotation speed on nugget structure and property was investigated in order to illuminate the process features. The results indicate that a notable increase of nugget size occurs at high rotation speeds of 5000–8000 rpm. With increasing rotation speed, the th...

摘要:We study conditions when a certain type of the Riesz Decomposition Property (RDP for short) holds in the lexicographic product of two po-groups. Defining two important properties of po-groups, we extend known situations showing that the lexicographic product satisfies RDP or even...
