This result is reformulated in terms of kernels of derivations on k-algebras A ⊂ B such that B is integral over A. Second we construct explicitly two examples of finite G-equivariant maps F. In the first one, F G is quasifinite but not finite. In the second one, F G is not...

We study norms and quasi-norms having large groups of isometries (uniquely maximal and almost transitive). It is shown that a uniquely maximal norm on a Ba... Fe Lix Cabello,Sa Nchez - 《Mathematical Proceedings of the Royal Irish Academy》 被引量: 37发表: 1998年 ...
We show that a group admits a non-zero homogeneous quasimorphism if and only if it admits a certain type of action on a poset. Our proof is based on a construction of quasimorphisms which generalizes Poincar\\'e--Ghys' construction of th... GB Simon,T Hartnick - 《Mathematics》 被引...

Ergodic Theory of ℤd Actions: The dynamical theory of tilings and Quasicrystallography Let \\pi : X -> S be a finite type morphism of noetherian schemes. A smoothformal embedding of X (over S) is a bijective closed immersion X -> \\frak{X},wh... EAJ Robinson 被引量: 54发表: ...
Let G be a finite group and ℱ a class of finite groups. We say that G is a quasi-ℱ-group if for every ℱ -eccentric chief factor H / K of G and every x ∈ G , x induces an inner automorphism on H / K . In this paper, the general theory of quasi-
It follows that G is quasisimple. By [13, Table 4.1], the Schur multiplier of A5 is a cyclic group of order 2, a contradiction. Hence NU∞(G)≠ZN∘U(G). Besides, we currently do not know whether the converse of statement (1) of Theorem B is true or not. Theorem C Let F ...
