论文摘要
我们研究了封闭的定向歧管,其拓扑复杂性最多是3,并确定它们的共同体环。对于某些可接受的共同体学环,我们还能够识别出与同构的相应流形。
We study closed orientable manifolds whose topological complexity is at most 3 and determine their cohomology rings. For some of admissible cohomology rings we are also able to identify corresponding manifolds up to homeomorphism.
