# COST Action 22113 – Kick-off meeting

This is the first official meeting of the COST Action (no. 22113) *“Fundamental challenges in theoretical physics”*. The meeting provides a chance for participants of this program to meet, to get acquainted with the topics they are working on, and to learn from the lectures and discussions with prominent invited speakers.

Dates: **May 13-15, 2024**

Place: **University of Padova**

**Public talk**

**Stanislav Smirnov** (University of Geneva)

**“Tiles and puzzles”**

Monday, May 13, 17:30 – Aula Magna, Palazzo del Bo

Abstract: *Suppose we are given (an infinite supply of) a few different tiles (puzzle-pieces). Can one tile the whole plane? How many tilings will there be for a given area? If there are many, how a random one will look like? We will discuss how even for simple tiles, like two different polygons, these problems become very interesting and relate to many areas, from logic to statistical physics.*

**Poster session and best poster prize**

Participants presenting a poster may be eligible for a best poster prize, of the amount of 600 Euro before tax (unless they opt out). The eligibility criteria are 1) being a member of the Action 2) not holding a tenured or tenure-track position and 3) not being a member of the Action Management Committee or Core Group. The posters will be evaluated during the event by a panel consisting of members of the Action Core Group who are present at the meeting.

**Venue and accommodation**

The meeting’s activities will take place in the city centre of Padova (for reference, close to Piazza Antenore). Participants (including speakers) are requested to arrange their own accommodation. A few hotels in the area are:

– Hotel Majestic Toscanelli **** – An elegant hotel in the city centre (5 min walk)

– Albergo Verdi *** – A comfortable hotel in the city centre (10 min walk)

– Hotel Donatello *** – A comfortable hotel in a nice area of town (10 min walk); we have a 15% discount code for reservations made before April 13

– Hotel Giotto *** – A budget hotel in a nice area of town (10 min walk)

– Hotel Casa del Pellegrino *** – A budget hotel used by pilgrims of St Anthony (10 min walk)

– Hilton Garden Inn **** – A modern hotel just outside the center (15 min walk)

Tip: in Padova it is easy to get a good simple breakfast in a cafe for 3 Euro or so (coffee and pastry, and 3 Euro more for some fresh juice); it’s usually not worth paying for hotel breakfast unless you are very keen on having eggs and bacon.

**Arrival information**

Padova is well-connected to long-distance trains through a high-speed line. The closest airport is Venice Marco Polo Airport. The cheapest way to reach Padova (station) from Marco Polo airport is the public operated bus service, which costs 10 Euros, see here for the schedule. The fastest way is a chauffeur service which takes about 40-45min and costs around 90 Euro; you can book by emailing for instance this service landomas@landomas.it. Shared transportation (shuttle) costs around 40 euros, see for instance here.
