In this paper we consider the conformal group of the unit sphere S, the proper Lorentz group Spin(1, n), for the study of spherical continuous wavelet transforms. The parameter space is determined by the factorization of the gyrogroup of the unit ball by an appropriate gyro-subgroup. We study two families of sections that give rise to anisotropic conformal dilation operators for the unit sphere...
we investigate compact composition operators on ceratin lipschitzspaces of analytic functions on the closed unit disc of the plane.our approach also leads to some results about compositionoperators on zygmund type spaces.
We describe the dynamics of magnetic skyrmions in synthetic antiferromagnets (SAF), with a finite interlayer coupling. Due to opposite gyrovector two SAF layers, coupled reach stationary regime spatial separation, direction orthogonal their velocity. As consequence, and contrary ferromagnetic situation, transient necessarily occurs, acceleration, related an inertia, that limits its time respons...
این پایان نامه در سه فصل نوشته شده است، در فصل اول تعاریف و قضایای لازم برای فصل های دوم و سوم بیان شده است. فصل دوم به بررسی عملگرهای ترکیبی وزن دار روی فضاهای توابع اندازه پذیر اختصاصداده شده است. فصل سوم که در واقع اصلی ترین فصل پایان نامه است به بیان نرم اساسی عملگر ترکیبی روی فضاهای ارلیز می پردازد. این پایان نامه بر اساس مقالات زیر تدوین گردیده است: • m. r. jabarzadeh the essential...
در این رساله ابتدا اطلاعاتی پایه ای و مفید درباره ی فضای ضرب داخلی ، فضای هیلبرت ، فضای نرم دار و فضای باناخ بیان شده و در فصل دوم اطلاعاتی راجع به فضای دوگان وعملگرهای خطی بیان شده و در فصل سوم با تجزیه و تحلیل دقیق مقاله a gruss type inequality for sequences of vectors in normed linear spaces and application یک نامساوی دیگر نوع گراوس روی فضاهای خطی نرم دار ارائه واثبات می گردد. وکاربرد آ...
the space now known as complete erdos space ec was introduced by paul erdos in 1940 as the closed subspace of the hilbert space ?2 consisting of all vectors such that every coordinate is in the convergent sequence {0} ? { 1 n : n ? n}. in a solution to a problem posed by lex g. oversteegen we present simple and useful topological characterizations of ec. as an application we determine the ...
We report on the very early time search for an optical afterglow from GRB 971227 with the Livermore Optical Transient Imaging System (LOTIS). LOTIS began imaging the ‘Original’ BATSE error box of GRB 971227 ∼ 14 s after the onset of gamma-ray emission. Continuous monitoring of the position throughout the evening yielded a total of 499 images (10 s integration). Analysis of these images revealed...
Motivated by recent work on integrable flows of curves and 1+1 dimensional sigma models, several O(N)-invariant classes of hyperbolic equations Utx = f(U,Ut, Ux) for an N -component vector U(t, x) are considered. In each class we find all scalinghomogeneous equations admitting a higher symmetry of least possible scaling weight. Sigma model interpretations of these equations are presented.
Several generalized Wallman type spaces are considered as well as various lattices of subsets therein. In particular, regularity of these lattices and consequences are investigated. Also considered are necessary and sufficient conditions for these lattices to be Lindel6f as well as replete, prime complete, and fully replete.
We prove the existence of designs of small size in a number of contexts. In particular our techniques can be applied to prove the existence of ndesigns on S of size Od(n d log(n)d−1).
