Paolo Emilio Ricci ((1944-02-04)4 February 1944) is an Italian mathematician, working on mathematical physics, orthogonal polynomials, special functions, numerical analysis, approximation theory and other related subjects mathematical analysis, theory of elliptic partial differential equations and special functions: he is also known for his work collaboration with Johan Gielis.
Education and academic career Paolo Emilio Ricci received his Laurea degree (cum laude) on 7 July 1967, at the Sapienza University of Rome: his thesis supervisor was Gaetano Fichera. After his graduation he was appointed assistant professor to the chair of Mathematical Analysis II again at the Sapienza University of Rome for the 1967-1968 academic year. From 1969 to 1980 he worked as an assistant to the same chair, except for the years 1970-71 when he did his military service as a second lieutenant in the Italian Corps of Military Engineers. In 1979 he won the ministerial competition for a chair of numerical analysis and become associate professor: as a consequence of his election, from November 1, 1980, to October 31, 1981, he worked as an ordinary professor of numerical analysis at the University of Catania. From November 1, 1981, to November 1, 1990, he held the chair of Mathematical Analysis I at the Faculty of Engineering of the Sapienza University of Rome, first as an assistant professor and after the 1983 as an ordinary professor. From 1990 to the year of his retirement (2009) he held the chair of numerical analysis at the Faculty of Natural, Physical and Mathematical Sciences of the Sapienza University of Rome: after his retirement he accepted professor position in the Università telematica internazionale Uninettuno, ad this is currently his work. He has also been director of the Rendiconti di Matematica in 1983 and for three years from 1984 to 1986 and then for six years, from 1987 to 1989 and from 1990 to 1992, jointly with Pietro Benvenuti.
Honors On 10 September 2003, he was awarded Doctor Honoris Causa by the I. Vekua Institute of Applied Mathematics of the Ivane Javakhishvili Tbilisi State University. On May 24-28, 2009, on the occasion of his retirement, the conference "Advanced Special Functions and Solutions of PDEs" in honor of Paolo Emilio Ricci was held in Sabaudia. In 2015, during the workshop "Modeling in Mathematics", for his contributions to geometry and mathematics, he was awarded the second Simon Stevin Prize for Geometry. In 2017, he received the "Life-long achievement award of Vijnana Parishad" of India, followed in 2022 by "Golden Jubilee Award of Vijnana Parishad of India". on the occasion of the 5th International Conference on Recent Advances in Mathematical Sciences with Applications in Engineering and Technology. On 23–24 May 2024, a conference in honor of Paolo Emilio Ricci on his 80th Birthday was held in Rome at the Istituto per le Applicazioni del Calcolo "Mauro Picone" IAC - CNR.
