Higher Diagonal Approximations and Skeletons of K ( w , l ) ' s
نویسنده
چکیده
Using the results of this paper one can compute the symmetric signature o(Sn/G) c Ln(~G) for any free action of a finite group G on S n . The symmetric signature appears in Ranicki's product formula for surgery obstructions. However, algebraic quadratic surgery shows that the product formula depends only on the chain level Poincare duality map (depending on A 0 defined below) and not on the higher diagonal approximations.

$varphi$-CONNES MODULE AMENABILITY OF DUAL BANACH ALGEBRAS
In this paper we define $varphi$-Connes module amenability of a dual Banach algebra $mathcal{A}$ where $varphi$ is a bounded $w_{k^*}$-module homomorphism from $mathcal{A}$ to $mathcal{A}$. We are mainly concerned with the study of $varphi$-module normal virtual diagonals. We show that if $S$ is a weakly cancellative inverse semigroup with subsemigroup $E$ of idemp...
متن کاملSemigroups with inverse skeletons and Zappa-Sz$acute{rm e}$p products
The aim of this paper is to study semigroups possessing $E$-regular elements, where an element $a$ of a semigroup $S$ is {em $E$-regular} if $a$ has an inverse $a^circ$ such that $aa^circ,a^circ a$ lie in $ Esubseteq E(S)$. Where $S$ possesses `enough' (in a precisely defined way) $E$-regular elements, analogues of Green's lemmas and even of Green's theorem hold, where Green's relations ${mathc...
متن کاملCommon Fixed Points and Invariant Approximations for Cq-commuting Generalized nonexpansive mappings
Some common fixed point theorems for Cq-commuting generalized nonexpansive mappings have been proved in metric spaces. As applications, invariant approximation results are also obtained. The results proved in the paper extend and generalize several known results including those of M. Abbas and J.K. Kim [Bull. Korean Math. Soc. 44(2007) 537-545], I. Beg, N. Shahzad and M. Iqbal [Approx. Theory A...
متن کاملLow Rank Off-diagonal Block Preconditioners for Solving Sparse Linear Systems on Parallel Computers
For a sparse linear system Ax = b, preconditioners of the form C = D + L+ U , where D is the block diagonal part of A (or incomplete factorization approximation of its blocks), and L and U are block strictly lower and upper triangular matrices composed of low-ranks approximations of the respective blocks of A, are examined. C is applied directly, by solving Cz = w, or partially, by applying one...
