对于K(a)hler曲面(M,g)上的β-辛临界曲面∑,如果存在q>3使得Lq(∑)有界,那么我们对∑上的K(a)hler角给出一个上界估计,该估计只依赖于M,q,β和∑的Lq泛函.当q>4时,这个估计是已知的,我们的结果推广了q的范围. 相似文献

The author obtains the theorems of Barth-Lefschetz type on Kahler manifolds with partially positive bisectional curvature without the assumption of nonnegative bisectional curvature. Some applications of the results to holomorphic mappings are given. 相似文献

The generalization of geometric phase for the quantum systems described by quaternionic quantum mechanics is given. The geometry of the quantum cyclic evolution is studied and the quaternionic Berry phase is shown to be given by the holonomy of the suitably defined fiber bundle. 相似文献

We consider the problem of identifying boundary values of holomorphic functions on bounded domains in ℂ2. We use the quaternionic analysis techniques to extending the CR structure to a pure function theoretical nature. The advantage of our procedure lies in the fact that it also runs for domains
with fractal boundary. 相似文献

We extend previous results by Albeverio, Iwata and Schmidt on the construction of a convergent lattice approximation for invariant scalar 3-vector generalized random fields F of an infinitely divisible type and apply them to the construction of convergent lattice approximation for the generalized random vector field A determined by the stochastic quaternionic Cauchy–Riemann equation A = F. 相似文献

Let M be a positive quaternionic Kahler manifold of dimension 4m. We already showed that if the symmetry rank is greater than or equal to [m/2] + 2 and the fourth Betti number b4 is equal to one, then M is isometric to HPm. The goal of this paper is to report that we can improve the lower bound of the symmetry rank by one for higher even-dimensional positive quaternionic Kahler manifolds. Namely, it is shown in this paper that if the symmetry rank of M with b4(M) = 1 is greater than or equal to m/2 + 1 for m ≥ 10, then M is isometric to HPm. One of the main strategies of this paper is to apply a more delicate argument of Frankel type to positive quaternionic Kahler manifolds with certain symmetry rank. 相似文献

For a positive integer n let Cl0,n be the universal Clifford algebra with the signature (0,n). The name Clifford analysis is usually referred to the function theories for functions in the kernels of the two operators: the (Cliffordian) Cauchy–Riemann operator and the Dirac operator. For n=2, Cl0,2 becomes the skew‐field of Hamilton's quaternions for which the two operators are widely known: the Moisil–Théodoresco and the Fueter operators. We establish the precise relations between the Moisil–Théodoresco operator and the Dirac operator for Cl0,3. It turns out that the case of the Cauchy–Riemann operator for Cl0,3 and the Fueter operator is more sophisticated, and we describe the peculiarities emerging here.

设M是复流形,具有复(α,β)度量F=αφ(|β|/α),其中α为M上的Hermite度量,β为M上的(1,0)形式。本文得到与F相联系的复非线性联络系数Гiμ^i的表达式,且证明了:若β为M上的全纯(1,0)形式,并且关于α的Hermite联络γij^k(z)平行,则F是M上的复Berwald度量;若α是M上的Kaihler度量,则F是M上的强Kahler Finsler度量. 相似文献

We construct bases of polynomials for the spaces of square‐integrable harmonic functions that are orthogonal to the monogenic and antimonogenic ‐valued functions defined in a prolate or oblate spheroid. 相似文献
