The seventh workshop
Graph Embeddings and Maps on Surfaces
Podbanské, Slovakia
30 July – 4 August, 2017

GEMS 2017

is the workshop organised by

Slovak Academy of Sciences, Banská Bystrica

Comenius University, Bratislava

Slovak University of Technology, Bratislava


Slovak Mathematical Society

The workshop is the seventh in the series of Slovak GEMS workshops. The previous workshops were held in 1994 (Donovaly), 1997 (Banská Bystrica), 2001 (Bratislava), 2005 (Stará Lesná), 2009 (Tále), and 2013 (Smolenice). For more than twenty years, map-theoretic community has been meeting every year. Timings and places have been stabilised, with a period of 4 years, on New Zealand (in the years congruent to 0 mod 4), Slovakia (1 mod 4), some other places (2 mod 4), and Slovenia (3 mod 4).

The workshop should bring together people interested in various aspects of graphs embedded on surfaces. The programme will consist of lectures by invited speakers and short talks by participants. Contributed talks should be related to one or more of the following topics:

  • Embeddings of graphs on surfaces
  • Symmetrical embeddings, regular maps
  • Group actions on graphs
  • Representativity and graph minors
  • Convex polytopes and polytopal graphs
  • Dessins d’enfants
  • Enumeration of maps

  • Marston Conder, University of Auckland, New Zealand
  • Robert Jajcay, Comenius University, Bratislava, Slovakia
  • Klavdija Kutnar, University Primorska, Koper, Slovenia
  • Cheryl Praeger, University of Western Australia, Perth, Australia
  • Egon Schulte, Northeastern University, Boston, U.S.A.
