José Carlos Petronilho, 1965-2021

CMUC deeply regrets the unexpected passing of Professor José Carlos Petronilho on August 27. He dedicated his entire academic career as a professor and researcher to the UC and the Department of Mathematics, which he joined in 1989. A member of CMUC's research group in Analysis, he devoted much of his research work to the study of Orthogonal Polynomials and Special Functions. He will be missed very much.

Verão com Ciência 2021

Challenges in Computational Mathematics, September 2021, Coimbra

The Lab for Computational Mathematics of CMUC supervises 7 internships for undergraduate and MSc students, as part of the project "Challenges in Computational Mathematics", sponsored by FCT programme "Verão com Ciência 2021".

The project, organized by our colleagues Sílvia Barbeiro and Adérito Araújo, takes place during the current month of September, and closes with a workshop on "Computational Mathematics in the challenges of the real world", with invited speakers and a session where students may present their work.

The topics of the internships range from "A watermark scheme for digital images", "Computational enumeration of negatively autopolar polyhedra" or "Data classification" to "Encryption/Cryptanalysis, RSA public key cipher".

The TACL conference has been held every two years since 2003. Since 2013 a summer school has been associated to the conference.

The week is organized around four advanced courses on central themes of TACL. Besides, a session with short presentations by students or a poster session may be organized.

Invited Lecturers:
• Dirk Hofmann (Univ. Aveiro, Portugal)
• Rosalie Iemhoff (Utrecht Univ., The Netherlands)
