This book presents an arithmetic treatment of some problems in analysis situs, which is the study of the properties of geometric objects that are invariant under continuous transformations. A problem in this field that had yet to be solved was the question of whether a closed curve in two-dimensional space divides the plane into an interior and an exterior region. The author introduces a set of axioms and arithmetic principles for analysis situs and proceeds to prove the theorem that a simple closed curve divides the plane into two regions, an interior, and an exterior. Next, the author extends this theorem to three-dimensional space, proving that a simple closed surface divides space into two regions, an interior and an exterior. The book concludes with a discussion of unilateral and bilateral surfaces, and the orientation of surfaces. It also provides the basis for extending the work to more than three dimensions. Anyone interested in analysis situs will find this a stimulating and thought-provoking work.
