General information

Scientific program

Important dates



- well-posedness, optimality and stability of
problems in optimization;

- calculus of variations, variational analysis;

- optimal control and stabilization;

- variational principles in optimization;

- regularization techniques for ill-posed problems;

- numerical optimization methods and their stable behavior under perturbations.

The workshop is a continuation of a series of meetings with the same title that was initiated in 1987 in Milan, Italy, by a small group of Bulgarian and Italian mathematicians working in the field of Well-Posedness in Optimization and Related Topics. The subsequent editions of the workshop were held in Sofia (1989), Santa Margherita Ligure (1991), Sozopol (1993), Marseille (1995), Sozopol (1997), Gargnano (1999), Warsaw (2001), Marseille (2003), Borovets (2005), Alicante (2007), Levico Termi (2009), Borovets (2011) and Borovets (2018), where the scope and the attendance were substantially enlarged.

The aim of the series of workshops is to bring together people that are interested in stability of optimization problems in a broad sense. In particular, the organizers want to attract young researchers to that area. Throughout the years the workshops have become broader in scope covering variety of topics in Variational Analysis, Topological and Functional Analytic Methods in Optimization, Optimal Control, and related applications.
