报告摘要1:Let A be an algebra over a _eld k. If C is an ideal of A and B _= A=C, then A is called an extension of B by C. By using the Grobner-Shirshov bases theory, we give completely
characterizations of the extensions of associative and Lie algebras respectively.
报告摘要2:Let G be a finite group and H is a subgroup of G. We call H has the cover-avoidance property in G , H is a CAP subgroup of G in short, if H either covers or avoids every chief factor of G. We give the structure of a finite group G under the assumption that some subgroups have the cover-avoidance property.
