The workshop will be focused on various types of graph colorings with distance, neighborhood or face constraints, such as packing coloring, strong and semi-strong edge coloring, dynamic edge coloring, face colorings, vertex distinguishing coloring, conflict-free coloring, unique-maximum coloring etc. The aim of the workshop is to discuss some open problems on various types of colorings as well as approaches, methods and techniques. The program consists of lectures followed by discussions, research in small groups and individual work. The attendance on this workshop is by invitation only.


Location

Workshop will take place in hotel Hviezdoslav in Kežmarok, a historic town located on the eastern side of the High Tatras (Slovakia).
