Summary Generailzed Green's functions are kernels of integral operators with certain properties. Solution operators with these properties
are calledGreen's operators. Necessary and sufficient conditions for the existence of Green's operators are given for the general case, and for operators
on Banach spaces.

Some classes of pseudodifferential operators over the field ofp-adic numbers and local fields with discrete valuation are studied. Sufficient conditions for the Green's functions to be non-negative are found.Institute of Mathematics, Ukrainian Academy of Sciences.

A generalization is given of the relations and equivalences on a semigroup S associated with J. A. Green by introducing the
concepts of Green's pairs and generalized Green's theories first on an arbitrary set X and finally on a semigroup S. Most
of the results about the usual Green's relations and equivalences are proved, and it is shown that previous generalizations
obtained by Wallace, Anscombre, Marki and Steinfeld, and Pastijn may be obtained as special cases of the theory developed.

本文在余代数上定义了五类等价关系,它们是Green等价G,D,L,R,H.然 后给出了这些等价关系一些基本性质和结构特点.在每个Green等价的等价类集上构 造了一种偏序并给出了偏序上半格和格结构的刻划.用G-,L-,R-类分别给出了子余 代数、左余理想、右余理想的结构刻划.进一步地,本文研究了张量积上的Green等 价以及余代数同态的Green保持性和提升性.作为应用,本文得到了两个不可约余代 数的张量积仍为不可约余代数的一个条件;证明了不可约余代数在G-保持余代数同 态下的同态像是不可约的. 相似文献

Summary We present a method in which the given boundary conditions are replaced by integral boundary conditions, so chosen that the Green's function can be constructed without changing the principal spectral properties of the operator.Translated from Litovskii Matematicheskii Sbornik, Vol. 13, No. 1, pp. 109–114, January–March, 1973. 相似文献

Associated to an -dimensional integral convex polytope is a toric variety and divisor , such that the integral points of represent . We study the free resolution of the homogeneous coordinate ring as a module over . It turns out that a simple application of Green's theorem yields good bounds for the linear syzygies of a projective toric surface. In particular, for a planar polytope , satisfies Green's condition if contains at least lattice points.
