General Information

The Workshop will take place 22-26 June 2015 at the Mathematical Institute of the LMU in Munich. The talks will begin on Monday morning and the final talk will be on Friday before lunch. Some funding is available for young researchers and PhD-students.


Registration is now closed.

Workshop Outline

The following definition of wrinkles is taken from Merriam-Webster's online dictionary:

wrin⋅kle noun \'riŋ-kəl\

In geometry, wrinkles are useful for proving h-principles. This technique was introduced by N. Mishachev and Y. Eliashberg in a series of three papers. It provides an efficient construction of families of maps with simple singularities. Such maps play an important role in differential topology (Morse functions, submersions, immersions, etc.). So far, the most well known applications of wrinkling include proofs of the following results: The principal aim of this workshop is to provide an introduction to the theory of wrinkling together with some of these applications.

Invited speakers




All talks take place in room 349 on the third floor of Theresienstr. 39 with the exception of the Colloquium talk of Emmy Murphy on Thursday, which will take place in A027.

Local information

How to get here

From the airport it is easiest to take the s-Bahn (S1 or S8). Both travel into the city and their direction is unique. There are ticket machines on the platform at the station. To get to the math department change to the 27 Tram at Karlsplatz Stachus going to Petuelring (see this map). Or if the weather is nice you may just want to walk.

From the main train station (Hauptbahnhof) either walk to Karlsplatz Stachus and take the tram, take the 100 Bus to the stop Pinakotheken (see this map) or take a (15-20 Minute) walk.


Please make sure to book a hotel room well in advance as there will be a trade fair during the week of the workshop. Here is a list of possible hotels.

Possibilities for lunch
