摘要
本文用组合算法Topdown证明了单项代数中循环的某些性质,从中可推得一些已知结果,因而给出了它们简单的组合证明.
The objective of this note is to use the combinatorial algorithm Topdown to show some properties of cycles in a monomial algebra,from which some well-known results are deduced immediately,providing very short combinatorial arguments to them.
