Homomorphisms between diffeomorphism groups
Homomorphisms diffeomorphism groups Geometric Topology
2012/6/25
For r at least 3, p at least 2, we classify all actions of the groups Diff^r_c(R) and Diff^r_+(S1) by C^p -diffeomorphisms on the line and on the circle. This is the same as describing all nontrivial ...
Homomorphisms of abelian varieties over geometric fields of finite characteristic
Homomorphisms of abelian varieties geometric fields of finite characteristic
2011/2/25
We study analogues of Tate’s conjecture on homomorphisms for abelian varieties when the ground field is finitely generated over an algebraic closure of a finite field. Our results cover the case of ab...
We introduce some equivalent notions of homomorphisms between quantum groups that behave well with respect to duality of quantum groups. Our equivalent definitions are based on bicharacters, coactions...
Suppose that $X$ and $Y$ are surfaces of finite topological type, where $X$ has genus $g\geq 6$ and $Y$ has genus at most $2g-1$; in addition, suppose that $Y$ is not closed if it has genus $2g-1$. O...
Approximate Representations and Approximate Homomorphisms
Approximate Representations Approximate Homomorphisms

Approximate algebraic structures play a defining role in arithmetic combinatorics and have
found remarkable applications to basic questions in number theory and pseudorandomness.

Let GL(V ) be a quasisimple classical group in its natural representation over a finite vector space V , and let = NGL(V )().
A Topological Version of the Borel-Tits Theorem on Abstract Homomorphisms of Simple Algebraic Groups
Topological Version Borel-Tits Theorem Simple Algebraic Groups
2010/12/9
In this paper, we produce topologized versions of two theorems. One is due to Borel and Tits [2] and is concerned with abstract homomorphisms of absolutely almost simple algebraic groups.
Derivations as Homomorphisms and Anti-homomorphisms on Lie Ideals (在Lie理想上为同态和反同态的导子)
素环 Lie理想 导子 同态 反同态

设$R$是2-扭自由的素环,$Z$是它的中心,$U$是它的Lie理想.如果$d$是$R$的一个导子,并且在$U$上是同态或反同态,则$d=0$,或者$U\subseteq Z$.此结果改进了Asma, Rehman,以及Shakir的一个定理.
Equivariant Kasparov theory and generalized homomorphisms
Equivariant Kasparov theory generalized homomorphisms
2010/10/29
Let G be a locally compact group. We describe elements of KK^G (A,B) by equivariant homomorphisms, following Cuntz's treatment in the non-equivariant case. This yields another proof for the universal...
