In this article, with the help of three axioms (Definition 3.1), the notion of abstract morphisms is introduced (see [1,2]). It will be proven that Hausdorff topological spaces together with abstract morphisms create a category on which the functor of ÄŒech homology is extended.

Consider any positive integer n. If n is even, halve it. If n is odd, multiply it by 3 and add 1. This algorithm is then repeated indefinitely. It has been conjectured by Collatz that this process, which is also known as Hasse’s algorithm, eventually reaches 1. A new perspective...

Liquid storage tanks are critical elements in the water supply scheme and firefighting system in many industrial facilities for storage of water, oil, chemicals and liquefied natural gas. A common effective method to reduce the seismic response of liquid storage tanks is using ba...
