The Opening Ceremony of the Academic Days of Cluj-Napoca 2019 will hold on May 16, 2019 (an announcement will be posted at Cluj-Napoca Branch of the Romanian Academy)

On April 16, 2019, 09:00, our Institute organizes the Symposium

Numerical Analysis, Approximation and Modeling.

The Symposium will be held at “Biblioteca Academiei Române“, first floor. Address: str. Kogălniceanu, no. 12-14.
