Faculty of Mathematics and Informatics at the Sofia University "St. Kliment Ohridski" and Institute of Mathematics and Informatics at the Bulgarian Academy of Sciences 14-th International Workshop on Well-Posedness of Optimization Problems and Related Topics August 20-24, 2018, Borovets, Bulgaria The aim of the series of workshops has been and still is to bring together people that share common interests in the general area of stability of optimization problems in a broad sense, and in particular younger researchers interested in this area. Although the workshops have kept its original name, they has gradually become much larger in scope as one of the well-established international meetings in Variational Analysis, Topological and Functional Analytic Methods in Optimization, Optimal Control, and related Applications. We are proud to [...]

      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), Borovets (2018) and Borovets (2021), 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 [...]
