Hervé Le Ferrand

Hervé Le Ferrand is a Lecturer at the Université de Bourgogne within the Faculty of Science and Technology, Department of Mathematics. His research primarily focuses on the history of mathematics, numerical analysis, and applied mathematical methodologies, with particular emphasis on algebraic continued fractions, Padé approximants, and vector-valued rational interpolation. He has extensively documented the scientific contributions of Robert de Montessus de Ballore, notably analyzing the 1902 convergence theorem that remains influential in mathematical literature.

• Academic Leadership: Member of the Statistics, Probability, Optimization and Control team at the Institut de Mathématiques de Bourgogne.
• Teaching: Develops educational materials for advanced mathematics courses including Calcul Intégral, Mathématiques pour l'Informatique, and Expression Écrite et Orale at L1-L3 levels.

Research Trajectory spans from foundational work in vector iteration functions (1995) to recent historical analyses of Paul Mansion's mathematical bibliography (2019). His publications demonstrate a unique blend of numerical algorithms and historiographical rigor, particularly in tracing the evolution of algebraic continued fractions and their modern applications.

Scientific Recognition includes:

• Inclusion of his 2016 article on Paul Appell in The Best Writing on Mathematics 2017 (Princeton University Press)
• Co-organizer of the 2017 Les sciences dans la famille de Montessus colloquium at Académie des Sciences de Dijon

Publication Trends reveal expertise in:

• Numerical Analysis (QD algorithm, vector iterations, convergence acceleration)
• Historical Mathematics (Montessus de Ballore's theorem, Belgian mathematicians like Paul Mansion)
• Matrix Theory (Gram determinants, orthogonal polynomials)

Academic Journey reflects comprehensive training through:

• 1980: Baccalauréat C
• 1985: CAPES de Mathématiques
<1986: Agrégation de Mathématiques
• 1989: DEA (M2) at Lille
• 1992: PhD in Numerical Mathematics under J. Van Iseghem at Université de Lille 1
