Brief Description:

A brief description of the Most Popular Topics of this Release are: Clearly Mathematics or Mathematicians as the Main Topic, and of course the wider ones that includes them that are Sciences, and Scientits, or even a wider Personalities, then going to more specific Topics, one could spot Uruguayan Mathematiciansand Uruguayan Scientits, and inside this Topic, the Mathematicianbeing honoured in this Issue that is Engineer José Luis Massera, and Italianborn Uruguayan Mathematician who researched the Stability of Differential Equations, devloping New Notions of Stability, and Publishing Several Foundational Papers and  influential Textbooks on that Topic. His results on Periodic Differential Equations have been heavily cited and are referred to as Massera's theorem, and his work on the Converse to Lyapunov's Criterionis also influential, and contain the well known Massera's lemma. His textbook (Massera & Schäffer 1966) is also heavily cited.

Then, there are some Topics related with the personality of Engineer José Luis Massera, first, undoubtely the Engineeringas it was his Proffesional career, and also Politics, in particular Left-Wing Politics, as he was part of the Communist Party, in which was elected Deputyin 1962 and reelected in 1966. After that he participated in the foundation of the Frente Amplio, Left-Wing Party that since 2005was elected for National Goverment and succesively relected until present time.

Both Politicsand Scienceswere present during all his life. After being arrested on October of 1975and torturedby the Uruguayan Militar Dictatorship, a broad and vigorous international campaign demanded his liberation constantly, leading to his freedom on March of 1984.  During the 80s and 90s participated actively in discussions with European and Latin American authors on the vitality of communism and the need to renew the Marxist doctrine and politics, besides implementing in Uruguay Development Program of Basic Sciences to stimulate production scientific, and participated in the founding work of the Sciences Faculty of the University of the Republic. In the second half of the 90s he focused completely on Politicstask, organizing seminars on Marx at the Sorbonne, University of Paris Xand other academic centers.

 During his career he received the title of Doctor Honoris Causaof the universities; La Sapienza (Rome), Humboldt (Berlin), Nice, of Puebla, Quito, Technic of Budapest, San Andres (Bolivia), Havana, UFRJ (Rio de Janeiro)and the University of the Republic (Uruguay).

Then, looking at the desing of the Issue, the focus of it is a Portrait Picture of Engineer José Luis Massera, by the Photographer Eduardo Collings, an Uruguayan Photographer specialized in Scientific Photography, accompanied by a Graphical Representation of a Function in X and Y Axis.

Finally, regarding the desing too, this time about the Block desing, the same Graphical Representation of a Function in X and Y Axis is shown on Background and a short Biographyof Engineer José Luis Massera is placed below the stamps, written by Ernesto Mordecki, a Professor at the Centro de Matemática of the University of the Republic, Uruguay, that his research interests include Optimal stopping of stochastic processes and applications to finance, with witch received his Ph.D in Statistics of Stochastic Processes in 1994 from the Steklov Mathematical Institute, under the supervision of Albert Shiryaev.

If you consider that there are another topics in this stamp, that were not spot in this review, you are encouraged to telling me about them, so please do not hesitate to post a comment. I would appreciate your help very much.
