Tomaž Pisanski: Operations on oriented maps and maniplexes

Povzetek. In the past we have been using flag graphs and symmetry type graphs for studying certain operations on maps and their symmetries, such as truncation, dual, medial, chamfering, etc. Here we study similar operations on oriented maps. Certain new operations that can only be defined for oriented maps, such as snub, are also considered. In the oriented case the primary tools, i.e., flag graphs and symmetry type graphs, are substituted by arc graphs and oriented symmetry type graphs. Some ideas apply to operations on maniplexes and oriented maniplexes. (This was my intended talk for the AMS Seattle meeting in January 2016 that I had to cancel. It represents work in progress with Gordon Williams, Leah W. Berman and Steve Wilson.)

Po seminarju vabimo vse člane programske skupine P1-0294 na običajno kavo, kjer se bomo pogovorili o nekaterih izzivih, ki čakajo programsko skupino v prihodnjem letu.

Vesele praznike in srečno novo leto 2016!
