Princípio das gavetas e aplicações

Abstract

The drawers principle of the German mathematician Dirichlet also known as the Pigeons House Principle can be presented as a mathematical result and as a method of a proof. When used as a mathematical result, the principle of the drawers is quite simple and intuitive seeming that this principle has little applicability in solving problems in mathematics. However, when used as a test method, it becomes an important tool in solving various problems in mathematics, but this is what we will see in this work. The Dirichlet Drawer Principle was named after the mathematician often used this principle in his work in the nineteenth century.
