同构的概念在抽象代数中至关重要。

The concept of isomorphism is crucial in abstract algebra.

在这些日子里，拓扑这个天使和抽象代数这个魔鬼为各自占有每一块数学领域而斗争着。

Hermann Weyl In these days the angel of topology and the devil of abstract algebra fight for the soul of each individual matehmatical domain.

或许比这些新方法的引入更为引人注目的是抽象代数的公理化、概念化的方法以及其对整个数学学科的深远影响。

Perhaps even more striking than the advent of these ideas has been the acceptance of the axiomatic conceptual method of abstract algebra and its pervading influence throughout mathematics.
