For any subspace PV its type is introduced which is determined by the dimension, the index, the dimension of the definite part of P and in some cases also by the presence or the absence of a certain vector in P. It occurs that the orthogonal group O(V) acts transitively on the set ...

The lower example does not satisfy the lattice condition since some points have their nearest neighbor on the right, and some on the left. If one classifies all two-dimensional lattices according to their symmetry elements, it is possible to show that there are only five distinct types, as ...
Hence a supersolvable lattice (resp., its Stanley-Reisner ring) is Cohen-Macaulay. We... V Welker - 《European Journal of Combinatorics》 被引量: 18发表: 1995年 Nested set complexes of Dowling lattices and complexes of Dowling trees Given a finite group G and a natural number n, we ...
The particle is prepared in a superposition of being in the corner and one of its first neighbors. The solid red line corresponds to a particle in a seventh generation Sierpiński gasket with a symmetric initial configuration. The solid blue line corresponds to the anti-symmetric initial condition...
We consider a converse problem of reconstructing a nonlinear operator from its derivative. We try to treat the case, if possible, in which both domains and range of ... T Kawasaki - 《Math Japonica》 被引量: 3发表: 1997年 Lateral order on complex vector lattices and narrow operators In ...
The theory of continuous lattices traces its beginnings to the work of Dana Scott and of Jimmie Lawson. In the late 1960's, Scott was looking for mathematical models of the λ-calculus of Church and Curry. Since this logic is type free, ... MW Mislove - Springer Netherlands 被引量: 2...
A Monte Carlo method is used to study N×N×N simple-cubic Ising lattices with periodic boundary conditions and free edges. For both types of boundary conditions the position of the specific-heat maximum varies for large N as aN-λ, wher... Landau,P D. - 《Physical Review B Condensed ...
