<p>This book is designed for graduate students to acquire knowledge of dimension theory, ANR theory (theory of retracts), and related topics. These two theories are connected with various fields in geometric topology and in general topology as well. Hence, for students who wish to research subjects in general and geometric topology, understanding these theories will be valuable. Many proofs are illustrated by figures or diagrams, making it easier to understand the ideas of those proofs. Although exercises as such are not included, some results are given with only a sketch of their proofs. Completing the proofs in detail provides good exercise and training for graduate students and will be useful in graduate classes or seminars.</p><p>Researchers should also find this book very helpful, because it contains many subjects that are not presented in usual textbooks, e.g., dim <i>X</i> ¿<b>I </b>= dim <i>X</i> + 1 for a metrizable space <i>X</i>; the difference between the small and large in
