*Mathematisches Kolloquium*

*Prof. Ulrich Wagner (IST Austria): "Algorithmic and Combinatorial 
Aspects of Embeddings"*

**

/_Abstract:_///

/We discuss a number of open questions and results concerning (from a 
combinatorialist's point of view)
higher-dimensional analogues of graph planarity and crossing numbers, 
i.e., embeddings of finite simplicial complexes (compact polyhedra) into 
Euclidean space.
While embeddings are a classical topic in geometric topology, here we 
focus on algorithmic and combinatorial  aspects. Two typical questions 
are the following: /

/(1) Is there an algorithm that, given as input a finite k-dimensional 
simplical complex, decides whether it embeds in d-dimensional space? /

/(2) What is the maximum number of k-dimensional simplices of a 
simplicial complex that embeds into d-dimensional space?
Time permitting, we will also discuss some maps with more general 
restrictions on the set of singularities, e.g., without r-fold 
intersection points.
The talk will be of a survey-like nature and touch upon joint work with 
a number of colleagues: M. Cadek, X. Goaoc, M. Krcal, I. Mabillard, J. 
Matousek, P. Patak, Z. Safernova, F. Sergeraert, E. Sedgwick, M. Tancer, 
and L. Vokrinek**/
