On $\check{H}^n$-bubbles in n-dimensional compacta

Umed H. Karimov,Dušan Repovš-1998-01-01-Colloquium Mathematicum

TL;DRAbstract

A topological space X is called an $\check{H}^n$-bubble (n is a natural number, $\check{H}^n$ is Čech cohomology with integer coefficients) if its n-dimensional cohomology $\check{H}^n(X)$ is nontrivial and the n-dimensional cohomology of every proper sub
