Jorge Sotomayor Tello

Jorge Manuel Sotomayor Tello (born 25 March 1942 in Lima) is a Peruvian-born Brazilian mathematician working on differential equations.^[2]

He earned his Ph.D. from the IMPA in 1964 under the supervision of Maurício Peixoto.^[2][3][4]

He is a recipient of Brazil's National Order of Scientific Merit in mathematics.^[5] Since 1994 he has been a member of the Brazilian Academy of Sciences.^[2]

He is the author of the textbooks Lições de Equações Diferenciais Ordinárias and Curvas Definidas por Equações Diferenciais no Plano. He has also translated essays of Henri Poincaré into Portuguese, which were published on a book under the title Um Poeta, um Matemático e um Físico: Três Ensaios Biográficos por Henri Poincaré.
