The Memoirs of the Weeks of Mathematics were first published in 2009, as a part of the activities of the Weeks of Mathematics. This first number compiled several works of diverse nature that corresponded to talks delivered during the first four Weeks of Mathematics. One year later, the release of “Memorias de la 5GSNM” confirmed that the works presented in the Weeks of Mathematics deserved to be published and spread through the Mexican mathematical community. Hence, the series “Matemáticas y sus aplicaciones” was born in 2011. Since then, this publication has been become a strong means of dissemination of the works of both faculty and students that take part in this yearly mathematical activity.
