       The Concurrency, Specification, and Programming (CS&P) workshop is one of a series of
seminars organized every even year by Humboldt University of Berlin and every odd year by the
University of Warsaw. This year’s edition of the conference is co-organized by the University of Warmia
and Mazury and the University of Warsaw.

       This year’s edition of the CS&P conference was dedicated to the memory of Professor Helena
Rasiowa. During a special session, memories prepared by the conference participants were presented.

Those memories are also published at http://csp2019.uwm.edu.pl/index.php/remembering-
professor-helena-rasiowa/.



        This volume consists of the papers presented at the 28th International Workshop on
Concurrency, Specification and Programming (CS&P 2019), that took place on September 24-26 2019
in Olsztyn, Poland.

         This year's edition of the Workshop resulted in 19 works being accepted for presentation and
all of them are part of this volume.

       We would like to thank once again everyone who contributed with their participation and
work to the organization of this year's workshop.
