Cretan Waves
Department of Mathematics and Applied Mathematics, University of Crete
9–13 October 2023
Room E.324 (directions below)
Scope:
This workshop is aimed at bringing together experts in geometric hyperbolic PDE,
to discuss recent developments in the field and explore future directions.
We are also thrilled to celebrate the appointment of Demetrios Christodoulou
as honorary professor in the Department of Mathematics and Applied Mathematics
at the University of Crete.
The inauguration ceremony will take place on October 10 at 12:00 (amphitheater N. Petrides
– entrance from the ground floor of the department).
Everyone is welcome to attend the activities without registration.

Directions:
1. By taxi: Your hotel can call you a taxi. A large taxi stand can be found at
Plateia Kornarou.
Ask the driver to take you to "Panepistimio" and show him the pin of the
math department on the map.
Duration: 20 minutes.
2. Bus no. 11 (not 12!): There are regular circular routes all day long,
from the city center (bus stops Plateia Kornarou
– Agios Minas)
to the university campus
(bus stop Panepistimio).
From there, the math department is a 2 minute walk. Duration: 30 minutes.
[For general info on bus routes: mobile app "Moovit".]
Enter the math department and look to the signs for wing E.
Room E.324 is located one floor up, at the end of wing E.
