Keywords: Topological space, Homology, Retract, Homotopic Mapping, Deformation retraction, Contractible, absolute retract


The objective behind this work is how to bring clarity to a reader about the terms homotopy and cohomology and point out the similarities and differences between homotopy and cohomology.

It also tends to briefly describe these two terminologies to every reader especially mathematician who are interested in algebraic topology and the need to know how it exists.
