告摘要1LetA 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 theGrobner-Shirshov bases theory, we give completely

characterizationsof the extensions of associative and Lie algebras respectively.

 

告摘要2LetG be a finite group and H is a subgroup of G. We call H has thecover-avoidance property in G , H is a CAP subgroup of G in short, ifH either covers or avoids every chief factor of  G. We give thestructure of a finite group G  under the assumption that somesubgroups  have the cover-avoidance property.
