WebMar 2, 2024 · Algebraic topology-Deformation retraction. Let X be space, and X = U ∪ V, U, V be two arbitary sets. A ⊂ U and A is deformation retraction of U, then can we way A ∪ V is deformation retraction of X ? (Let the element of V fixed during the deformation). The core in this problem is that does the desired "deformation retraction" continuous?
