Robert Jajcay de la Universidad Comenius, Bratislava, Eslovaquia. Invitado de la Dra. Isabel Hubard Escalera para trabajar en torno al proyecto “Generalizations of Cayley graphs and maps to polyhedra, polytopes and maniplexes”.  Duración 184 días, del 01/08/2025 al 31/01/2026.

Prof. Robert Jajcay is one of the leading researchers in three research areas: Algebraic Graph Theory, Topological Graph Theory, and Extremal Graph Theory. He received his PhD. in 1995 from the University of Nebraska-Lincoln, and held a position with Indiana State University from 1995 to 2012, where he became a full professor in 2006. In 2012, he moved to the Comenius University in Bratislava, where he became a professor in 2022. Currently, he is a member of the Department of Algebra and Geometry, and associate dean for doctoral studies of the Faculty of Mathematics, Physics, and Computer Science. He has hosted five postdoctoral visitors, has been adviser to three PhD. students and is currently advising three more. He also advised 11 Master students (one of whom was awarded the Rector’s Prize of the Comenius University, and placed 1st in the Czech-Slovak round of student research competition) and 12 Bachelor students. He is the author of the Dynamic Survey on Cages, invited speaker at numerous international conferences, and one of the organizers of the weekly Algebraic Graph Theory seminar at the Faculty of Mathematics, Physics and Computer Science. He also has been the principal organizer of several conferences and workshops, invited organizer for a special session at the 8th Slovenian Conference on Graph Theory, June 21 - 27, 2015, Kranjska Gora, Slovenia, and was one of main organizers of the Algebraic Graph Theory International Webinar (AGTIW). His extended research visits took him to over 19 international institutions. He has published over 60 research articles in top research journals, was co-editor with J. Siran of Symmetries in Graphs, Maps, and Polytopes, 5th SIGMAP Workshop, published in the Springer Proceedings in Mathematics & Statistics 159 (2016) series, and is a member of the editorial board for Ars Mathematica Contemporanea, The Art of Discrete and Applied Mathematics, and Acta Mathematica Universitatis Comenianae. He is also a reviewer for Zentralblatt fur Mathematik (100) and Mathematical Reviews (60) and a referee for numerous journals and several books.
