We will discuss this question for triangulations of three-manifolds. In practice there is fast software to answer this question and theoretical ly the problem is known to be decidable. However\, our understanding is l imited and known theoretical algorithms could have extremely long run-time s. I will describe a programme to show that the three-manifold homeomorph ism problem is in the complexity class NP\, and discuss the important sub- case of Seifert fibered spaces.\n LOCATION:https://researchseminars.org/talk/GaTO/86/ END:VEVENT END:VCALENDAR
