The Fifteenth Katowice-Debrecen Winter Seminar on Functional Equations and Inequalities was held in the Mathematical Research and Conference Center Bedlewo, Poland, from January 28 to 31, 2015. It was organized by Stefan Banach International Mathematical Center. 14 participants came from the University of Debrecen (Hungary), 13 from the University of Silesia in Katowice (Poland) and one from each of the following universities: University of Miskolc (Hungary), Pedagogical University of Cracow, Kraków (Poland) and Vologda State University, Vologda, (Russian Federation) Professor Roman Ger opened the Seminar and welcomed the participants to Bedlewo. The scientific talks presented at the Seminar focused on the following topics: equations in a single variable and in several variables, iteration theory, equations on abstract algebraic structures, regularity properties of the solutions of certain functional equations, functional inequalities, Hyers-Ulam stability, functional equations and inequalities involving mean values, generalized convexity. Interesting discussions were generated by the talks. There was also a Problem Session and a festive dinner. The closing address was given by Professor Zsolt Páles. His invitation to hold the Sixteenth Debrecen-Katowice Winter Seminar on Functional Equations and Inequalities in February 2016 in Hungary was gratefully accepted. Summaries of the talks in alphabetic order of the authors follow in section 1 and the list of participants in the second section.(fragment of text)
