José Oswaldo Lezama Serrano (born 1956) is a
Early life and education
Lezama was born in
In 1984 he came back to Bucaramanga and started working as professor in the Industrial University of Santander. The next year he moved to Bogotá and since then has worked as full professor at the National University of Colombia. He held this position until 2020, year in which he retired. In 1993, Lezama received the TWAS Scholarship (Third World Academy of Sciences) as visitant professor in Trieste, Italy. That same year he also visited the University of Buenos Aires and the Instituto Argentino de Matemática under the financial support of CONICET and the second mentioned institute.[1]
Career
Since his return to Colombia, Lezama has had a very active participation in the mathematical community, taking part in national and international events as attendant, speaker and organizer. Between 1986 and 1991 started a research seminar on rings, modules and categories. As a result, in 1994 he published with the mathematician Gilma de Villamarín a book called ″Anillos Módulos y Categorías″. Until 2002 he also hosted a seminar in commutative algebra, called SAC (″Seminario de Álgebra Conmutativa″, in Spanish).[1][6]
With time his interest in noncommutative algebra grew until the mentioned seminar changed its name to SAC2 (″Seminario de Álgebra Constructiva″, in Spanish) and the research in such matter started. The first aboarded topics were noncommutative Gröbner basis and homological properties of noncommutative rings. In 2011, with his doctoral student Claudia Gallego, published for the first time the concept of skew PBW extension, which with time became his main topic of research.[1][6][7]
In 2017 Lezama received the National Award of the Colombian Mathematical Society, being the most notorious recognition of the country in the area.[2][3] In 2018 he received public attention when he published in several media an opinion article about the candidature of Sergio Fajardo to the presidency of Colombia.[8][9]
In 2020, coinciding with his year of retirement of the National University of Colombia, a book called ″Skew PBW Extensions″ was published in the editorial Springer summarizing the results obtained by Lezama and colleagues/students among the years.[7] Another notorious written work of Lezama are the called ″Cuadernos de Álgebra″ consisting on ten monographies (in Spanish) covering the basic topics of undergraduate and graduate abstract algebra, including Galois theory, algebraic geometry and homological algebra.[1][6]
