This book contains short notes or articles, as well as studies on several topics of Geometry and Number theory. The material is divided into ve chapters: Geometric theorems;Diophantine equations; Arithmetic functions; Divisibility properties of numbersand functions; and Some irrationality results. Chapter 1 deals essentially with geometricinequalities for the remarkable elements of triangles or tetrahedrons. Other themes havean arithmetic character (as 9-12) on number theoretic problems in Geometry. Chapter 2includes various diophantine equations, some of which are treatable by elementary methods;others are partial solutions of certain unsolved problems. An important method isbased on the famous Euler-Bell-Kalmar lemma, with many applications. Article 20 maynbsp;be considered also as an introduction to Chapter 3 on Arithmetic functions. Here manynbsp;papers study the famous Smarandache function, the source of inspiration of so manynbsp;mathematicians or scientists working in other elds. The author has discovered variousnbsp;generalizations, extensions, or analogues functions./p>
