New PDF release: Selected Chapters of Geomety, Analysis and Number Theory

The purpose of this ebook is to offer brief notes or articles, in addition to reports on a few subject matters of Geometry, research, and quantity thought. the fabric is split into ten chapters: * Geometry and geometric inequalities; * Sequences and sequence of genuine numbers; * unique numbers and sequences of integers; * Algebraic and analytic inequalities; * Euler gamma functionality; * capability and suggest price theorems; * useful equations and inequalities; * Diophantine equations; * mathematics services; * Miscellaneous topics.
