Professor of Mathematics, Faculty of Sciences of Sfax

Ali Baklouti is a Full Professor of Mathematics at the University of Sfax, Tunisia. He earned his Ph.D. in Mathematics from the University of Metz, France, in 1995. He served as Vice-President of the University of Sfax from December 2020 to July 2024 and held the position of President of the Tunisian Mathematical Society for two consecutive terms (April 2016–March 2019 and April 2019–March 2022). Since January 2012, he has been the Deputy Director of the Mediterranean Institute of Mathematical Sciences, an institution he co-founded that same year. In December 2016, he was elected as a permanent member of the Tunisian Academy of Sciences, Letters, and Arts.

Professor Baklouti has received numerous prestigious awards, including the AMU-PaCOM 2022 Award and Medal, Category A in Mathematics, and the Royal Society Africa Prize 2024. In the same year, he was also honored with the Order of Merit for Education and Teaching by the President of Tunisia.

He currently serves as Co-Editor-in-Chief of the Tunisian Journal of Mathematics (published by MSP, USA) and as Editor-in-Chief of Advances in Pure and Applied Mathematics (published by ISTE, UK). Additionally, he is a member of the editorial boards of other several journals, including the Graduate Journal of Mathematics (MIMS), and the Arabian Journal of Mathematics (Springer).

Abstract

Pr. Hideyuki Ishi
Abstract: A Lie group is said to be almost abelian if it has a codimension-one normal commutative subgroup. An almost abelian Lie group is a solvable Lie group with rather simple structure, whereas this class contains non-type I groups such as the Mautner group. We consider the case where an almost abelian group G is exponential solvable. Then we can describe all the irreducible unitary representations of G via the Mackey machine. We shall discuss a criterion for the triviality of the kernel of the infinitesimal representation of a generic irreducible unitary representation of G.

Pr. Marcello Lucia

Abstract: The second fundamental form that may arise by considering minimal immersions of a fixed surface in a space form is subjected to various analytical constraints. Among those one, a central role is played by the Gauss-Codazzi equations, for which we will present several results.
