Ideal boundary of 7-systolic complexes and groups

چکیده
The notion of k-systolic (k ≥ 6 being a natural number) complexes was introduced by T. Januszkiewicz and J. Świa̧tkowski [JS1] and, independently, by F. Haglund [H] as combinatorial analogue of nonpositively curved spaces. Those complexes are simply connected simplicial complexes satisfying some local combinatorial conditions. Roughly speaking there is a lower bound for the length of “essential" closed paths in a one-skeleton of every link.

Vertex Decomposable Simplicial Complexes Associated to Path Graphs
Introduction Vertex decomposability of a simplicial complex is a combinatorial topological concept which is related to the algebraic properties of the Stanley-Reisner ring of the simplicial complex. This notion was first defined by Provan and Billera in 1980 for k-decomposable pure complexes which is known as vertex decomposable when . Later Bjorner and Wachs extended this concept to non-pure ...
متن کاملSolution of Thermo-Fluid problems in Bounded Domains via the Numerical Panel Method
The classical panel method has been extensively used in external aerodynamics to calculate ideal flow fields around moving vehicles or stationary structures in unbounded domains. However, the panel method, as a somewhat simpler implementation of the boundary element method, has rarely been employed to solve problems in closed complex domains. This paper aims at filling this gap and discusses th...
متن کاملEffect of Non-ideal Boundary Conditions on Buckling of Rectangular Functionally Graded Plates
We have solved the governing equations for the buckling of rectangular functionally graded plates which one of its edges has small non-zero deflection and moment. For the case that the material properties obey a power law in the thickness direction, an analytical solution is obtained using the perturbation series. The applied in-plane load is assumed to be perpendicular to the edge which has no...
متن کاملThe fixed point theorem for simplicial nonpositive curvature
We prove that for an action of a finite group G on a systolic complex X there exists a G–invariant subcomplex of X of diameter 5. For 7–systolic locally finite complexes we prove there is a fixed point for the action of any finite G. This implies that free products with amalgamation (and HNN extensions) of 7–systolic groups over finite subgroups are also 7–systolic.
متن کاملComparison of hemodynamic changes of Propofol and Thiopental during
Introduction: General anesthesia is the most common technique for performance of various surgical procedures. Thiopental is the most common anesthetic agent for intravenous induction. Since the introduction of propofol as an anesthetic agent, its use has increased progressively and has become the drug of choice for induction of anesthesia in several conditions. The aims of this study were com...
