2 0 Ju l 2 00 6 GENERALIZED ORIENTATIONS AND THE BLOCH INVARIANT
For compact hyperbolic 3-manifolds we lift the Bloch invariant defined by Neumann and Yang to an integral class in K 3 (C). Applying the Borel and the Bloch regulators, one gets back the volume and the Chern-Simons invariant of the manifold. We also discuss the non-compact case, in which there appears a Z/2-ambiguity.
متن کاملBloch–periodic Generalized Functions
Bloch-periodicity is a generalization of the notion of periodic and antiperiodic functions with much practical relevance for engeneering science and especially condensed matter physics. In recent work we have considered this property in the setting of classical functional analysis, and also introduced the new notion of asymptotically Bloch-periodic functions. In this paper we formulate these pr...
متن کاملGeneralized colorings and avoidable orientations
Gallai and Roy proved that a graph is k-colorable if and only if it has an orientation without directed paths of length k. We initiate the study of analogous characterizations for the existence of generalized graph colorings, where each color class induces a subgraph satisfying a given (hereditary) property. It is shown that a graph is partitionable into at most k independent sets and one induc...
متن کاملideological and cultural orientations in translation of narrative text: the case of hajji baba of isfahan
در میان عواملی که ممکن است ذهن مترجم را هنگام ترجمه تحت تأثیر قرار دهند، می توان به مقوله انتقال ایدئولوژی از طریق متن یا گفتمان اشاره کرد. هدف از این تحقیق تجزیه و تحلیل جنبه های ایدئولوژیکی و فرهنگی متن مبدأ انگلیسی نوشته جیمز موریه تحت عنوان سرگذشت حاجی بابای اصفهانی ( 1823) و ترجمه فارسی میرزا حبیب اصفهانی(1880) بوده است.
Generalized Baer-Invariant of a Pair of Groups and the Direct Limit
In this paper we introduce the concept of generalized Baer-invariant of a pair of groups with respect to two varieties ? and ? of groups. We give some inequalities for the generalized Baer-invariant of a pair of finite groups, when ? is considered to be the Schur-Baer variety. Further, we present a sufficient condition under which the order of the generalized Baer-invariant of a pair of finite ...
