No, it was not Calyampudi Radhakrishna Rao who came to TéSA to tell us about his famous bounds (thanks Wikipedia for the picture), he unfortunately died in August 2023 at the age of 102 without having had time to visit us! But it was Sarah El Boulch, post-doctoral researcher at ISAE-SUPAERO who came to share with us the results of her work on “Hybrid and Modified Lower bounds for Discrete-time Markovian Dynamic systems“. Another very interesting seminar!
