The UMA is based in Santa Fe, Argentina, and is a member of the Mathematical Union of Latin America and the Caribbean [es].

[4] In its early years the driving force in the UMA was Julio Rey Pastor, who was later described by Luis Santaló as talented at creation and promotion, but inconsistent at execution.

[4]: 2  For example, the first edition of the Journal of the UMA was issued by a different publishing house than had been agreed at its founding, and listed the founders incorrectly on its front cover.

[4] The UMA holds an annual meeting, which from 1945 to 1975 was known as the Jornadas Matemáticas, and since then has been called the Reunión Anual.

[4] The UMA also publishes the Revista de Educación Matemática in partnership with the National University of Córdoba's department of mathematics, astronomy, physics, and computer science.
