Improper Actions and Higher Connectivity at Innnity
Given an improper action (= cell stabilizers are innnite) of a group G on a CW-complex X , we present criteria, based on connectivity at innnity properties of the cell stabilizers under the action of G that imply connectivity at innnity properties for G. A reenement of this idea yields information on the topology at innnity of Artin groups, and it gives signiicant progress on the question of wh...
متن کاملCommensurated Subgroups, Semistability and Simple Connectivity at Infinity
A subgroup Q of a group G is commensurated if the commensurator of Q in G is the entire group G. Our main result is that a finitely generated group G containing an infinite, finitely generated, commensurated subgroup H, of infinite index in G is 1-ended and semistable at ∞. If additionally, Q and G are finitely presented and either Q is 1-ended or the pair (G,Q) has 1 filtered end, then G is si...
متن کاملMultistep Methods Using Higher Derivatives and Damping at Infinity*
Linear multistep methods using higher derivatives are discussed. The order of damping at infinity which measures the stability behavior of a fc-step method for large h is introduced. ,4-stable methods with positive damping order are most suitable for stiff problems. A method for computing the damping order is given. Necessary and sufficient conditions for A -stability, A (a) -stability and stif...
متن کاملNovikov Conjectures for Arithmetic Groups with Large Actions at Infinity
We construct a new compactification of a noncompact rank one globally symmetric space. The result is a nonmetrizable space which also compactifies the Borel–Serre enlargement X of X , contractible only in the appropriate Čech sense, and with the action of any arithmetic subgroup of the isometry group of X on X not being small at infinity. Nevertheless, we show that such a compactification can b...
متن کاملConnectivity at Infinity for Right Angled Artin Groups
We establish sufficient conditions implying semistability and connectivity at infinity properties for CAT(0) cubical complexes. We use this, along with the geometry of cubical K(π, 1)’s to give a complete description of the higher connectivity at infinity properties of right angled Artin groups. Among other things, this determines which right angled Artin groups are duality groups. Applications...
