Let be a translation plane of odd order p2R for p a prime. Let admit at least two p-groups, Bi, i=1, 2, B1B2 of orders > pR/2 which fix Baer subplanes i, i = 1,2, 12 pointwise. It is shown that under these assumptions must be a Hall plane. 相似文献

For a bounded regular Jordan domain in R
2, we introduce and study a new class of functions K() related on its Green function G. We exploit the properties of this class to prove the existence and the uniqueness of a positive solution for the singular nonlinear elliptic equation u+(x,u)=0, in D(), with u=0 on and uC(), where is a nonnegative Borel measurable function in ×(0,) that belongs to a convex cone which contains, in particular, all functions (x,t)=q(x)t
–,>0 with nonnegative functions qK(). Some estimates on the solution are also given. 相似文献

LetV be a finite dimensional complex linear space and letG be a compact subgroup of GL(V). We prove that an orbitG, V, is polynomially convex if and only ifG
is closed andG is the real form ofG
. For every orbitG which is not polynomially convex we construct an analytic annulus or strip inG
with the boundary inG. It is also proved that the group of holomorphic automorphisms ofG
which commute withG
acts transitively on the set of polynomially convexG-orbits. Further, an analog of the Kempf-Ness criterion is obtained and homogeneous spaces of compact Lie groups which admit only polynomially convex equivariant embeddings are characterized.Supported by Federal program Integratsiya, no. 586.Supported by INTAS grant 97/10170. 相似文献

Zusammenfassung Es werden untere und obere Schranken für den tiefsten Eigenwert 1() der elastisch gestützten schwingenden Membran hergeleitet. Die elastische Bindung der Membran am Rande wird durch charakterisiert, und wird als Parameter betrachtet.Die Verwendung des klassischen Rayleigh-Prinzipes liefert obere Schranken, mit Hilfe eines konvexen FunktionalsJ() erhält man obere und untere Schranken. Eine Zerlegungsmethode endlich gibt eine untere Schranke für 1().

Summary This article is concerned with the determination of upper and lower bounds for the lowest eigenvalue 1() of the elastically supported vibrating membrane. The elastic support on the boundary is characterized by which is regarded as a parameter.The classical Rayleigh-Principle gives upper bounds. The use of a convex functionalJ() yields upper and lower bounds for 1(). A method of decomposition leads to a lower bound for 1().

Summary For a realization of lengthn from a covariance stationary discrete time process with spectral density which behaves like 1–2H
as 0+ for 1/2<H<1 (apart from a slowly varying factor which may be of unknown form), we consider a discrete average of the periodogram across the frequencies 2j/n,j=1,..., m, wherem andm/n0 asn. We study the rate of convergence of an analogue of the mean squared error of smooth spectral density estimates, and deduce an optimal choice ofm. 相似文献

We use Liouville spaces in order to prove the existence of some different fractional -Brownian motion ( 0 < 1 ), or fractional ( , )-Brownian sheets. There are also applications to the Wiener stochastic integral with respect to these -Brownian. 相似文献

Synthetic Domain Theory provides a setting for denotational semantics following Dana Scott's slogan domains as sets in which all functions are continuous. Several approaches can be found in the literature, but they are either model-dependent or if they use an axiomatic setting then not uniformly and not explicitly. We present a completely logical approach to Synthetic Domain Theory (SDT), axiomatizing (complete) Extensional PERs. On these grounds some basic domain theory is developed. Special attention is devoted to admissibility. The axiomatic approach is advantageous since it allows for easy formalization and comparison to other axiomatic settings.The consistency of the theory is shown by providing an appropriate realizability model. It is discussed how to get from this special kind of SDT {à la Scott} to a more general form which unifies several approaches. 相似文献
