The book "Immersion (Mathematics)" by Alphascript Publishing offers a comprehensive introduction to the concept of immersion in mathematics. It covers differentiable mappings between differentiable manifolds and explains how the derivative at each point is injective. The authors, Frederic P. Miller, Agnes F. Vandome, and John McBrewster, clarify the differences between immersions and embeddings and provide a detailed analysis of the conditions under which an immersion can be considered an embedding. The book is aimed at students and professionals seeking a deeper understanding of the mathematical concepts in this field. It is available in a paperback edition and was published in 2009.
