Nigel Kalton was an extraordinary mathematician and an important, influential source of inspiration for the Banext group at Extremadura -- not to mention how much those of us lucky enough to have met Nigel miss him. In May 2026, it will be twenty years since the fabulous Banach Spaces and their Applications in Analysis conference in honor of Nigel's 60th birthday, held at Miami University, Oxford, Ohio; and eleven since its follow-up at the CIRM in Luminy. Following that tradition, we are organizing this workshop focused on Banach space theory and related areas.
The workshop will be structured into four panels.
Panel 1. About Nigel's life and work.
Speakers: F. Albiac, J.M.F. Castillo, G. Godefroy, B. Radrianantoanina.
Panel 2. These ones Nigel didn't see coming.
Plenary lectures on results obtained after his passing that would probably have surprised him -- though this is hard to claim given his sharp mathematical intuition.
Speakers: J.L. Ansorena, F. Cabello Sánchez, V. Ferenczi, G. Lancien, G. Plebanek, N. de Rancourt, P. Scholze, P. Tradacete.
Panel 3. Advances on selected topics.
Invited talks about new advances in topics dear to Nigel.
Speakers: F. Baudier, B.M. Braga, W.H.G. Correa, W. Cuellar, A. Fovelle, R. Pino, F. Sukochev.
Panel 4. Communications from participants.
The Workshop will take place at the Instituto de Matemáticas de la Universidad de Extremadura, Badajoz, Spain, from Tuesday, May 19 until Friday, May 22, 2026.
