We show that FC-spaces due to Ding are particular types of L-spaces due to Ben-El-Mechaiekh et al., and hence particular types of G-convex spaces. Some counter-examples are given and related matters are also discussed. 相似文献

Summary We study some special types of slant submanifolds of S-manifolds related to the second fundamental form of the immersion: totally f-geodesic and f-umbilical, pseudo-umbilical and austere submanifolds. We also give several examples of such submanifolds. 相似文献

We show that the common identification of H with its dual space in the famous functional frame V ⊂ H = H′ ⊂ V′ is incompatible with the distributional frame for some standard pdes and we recall an error related to this unnecessary
identification which is repeated from years. 相似文献

Due to the fact that in the case q > 1 the q-Bernstein polynomials are no longer positive linear operators on C[0, 1], the study of their convergence properties turns out to be essentially more difficult than that for q < 1. In this paper, new saturation theorems related to the convergence of q-Bernstein polynomials in the case q > 1 are proved. 相似文献

Novikov superalgebras are related to quadratic conformal superalgebras which correspond to the Hamiltonian pairs and play

Existence and localization results are established for systems of second-order differential equations with p -Laplacian on finite and semi-infinite intervals. For a compact interval, the compression and expansion conditions that are
used are related to the first eigenvalue of the p-Laplacian. 相似文献

The aim of this paper was to derive new identities and relations associated with the q‐Bernstein polynomials, q‐Frobenius–Euler polynomials, l‐functions, and q‐Stirling numbers of the second kind. We also give some applications related to theses polynomials and numbers. Copyright © 2012 John Wiley & Sons, Ltd. 相似文献

We show a relation between systems of integrable tops on the algebras sl(N, ℂ) and Calogero-Moser systems of N particles. We construct classical Lax operators corresponding to these systems. We show
that these operators are related to certain new trigonometric and rational solutions of the Yang-Baxter equations for the
algebras sl(N, ℂ) and give explicit formulas for N = 2, 3.

In modern number theory there are famous theorems on the modularity of Dirichlet series attached to geometric or arithmetic
objects. There is Hecke’s converse theorem, Wiles proof of the Taniyama-Shimura conjecture, and Fermat’s Last Theorem to name
a few. In this article in the spirit of the Langlands philosophy we raise the question on the modularity of the GL2-twisted spinor L-function Z

(s) related to automorphic forms G,h on the symplectic group GSp2 and GL2. This leads to several promising results and finally culminates into a precise very general conjecture. This gives new insights
into the Miyawaki conjecture on spinor L-functions of modular forms. We indicate how this topic is related to Ramakrishnan’s
work on the modularity of the Rankin-Selberg L-series. 相似文献

We study the balayage related to the supersolutions of the variable exponent p(·)-Laplace equation. We prove the fundamental convergence theorem for the balayage and apply it for proving the Kellogg property,
boundary regularity results for the balayage, and a removability theorem for p(·)-solutions. 相似文献

Let G be a bipartite graph and g and f be two positive integer-valued functions defined on vertex set V(G) of G such that g(x)≤f(x). In this paper,some sufficient conditions related to the connectivity and edge-connectivity for a bipartite (mg,mf)-graph to have a (g,f)-factor with special properties are obtained and some previous results are generalized.Furthermore,the new results are proved to be the best possible. 相似文献

A natural extension of the Daugavet property for p-convex Banach function spaces and related classes is analysed. As an application, we extend the arguments given in the setting
of the Daugavet property to show that no reflexive space falls into this class. 相似文献

results generalize classical theorems on the standard contact metric structure of T

For a subadditive fuzzy measure (not assumed finite), a Minkowski type triangle inequality, with Choquet integrals in place
of Lebesgue integrals, is shown to hold. It is immediate that the set of functions for which a certain positive power of the
absolute values have finite Choquet integrals is closed under addition, leading to a linear space analogous to the Lebesgue
space L
p
, with a metric related to the integral of that power. Under the additional condition that the subadditive fuzzy measure is
inner continuous (Sugeno), the space is shown to be complete. Consequences of the Minkowski type inequality are illustrated
in two specific instances.

In [9], we proved numerically that spaces generated by linear combinations of some two-dimensional Haar functions exhibit
unexpectedly nice orders of approximation for solutions of the single-layer potential equation in a rectangle. This phenomenon
is closely related, on the one hand, to the properties of the approximation method of hyperbolic crosses and on the other
to the existence of a strong singularity for solutions of such boundary integral equations. In the present paper, we establish
several results on the approximation for the hyperbolic crosses and on the best N-term approximations by linear combinations of Haar functions in the H

-norms, −1 < s < 1/2; this provides a theoretical base for our numerical research. To the author's best knowledge, the negative smoothness

We develop a systematic approach to the study of independence in topological dynamics with an emphasis on combinatorial methods.
One of our principal aims is to combinatorialize the local analysis of topological entropy and related mixing properties.
We also reframe our theory of dynamical independence in terms of tensor products and thereby expand its scope to C*-dynamics. 相似文献
