查询词典 endomorphisms

Knauer in 1990 first defined the endomorphism spectrum and the endomorphism type of a graph to study the algebraic structure which is put on a graph by this various endomorphisms.

德国数学家Knauer于1990年在文献[1]中首次提出了自同态谱和自同态型的概念，目的是通过图的各种不同的自同态来研究图的代数结构。

Firstly, some basic properties of the limit shadowing are given; Secondly, we give the characterization of both lin-ear automorphisms and linear flows on R~ with the limit shadowing property; Thirdly, as applications we prove that the hyperbolic endomorphisms on T~ have the limit shadowing properties, Smale "horseshoes" have the same prop-...
