SIG VII - 18-30 June 2018

Open problems in Skyrmions

Lectures on topological solitons, their mathematical properties and physical applications.

As always, the aim of this informal workshop is to increase interactions (and possible future collaboration) between Skyrme oriented physicists and mathematicians. So, we are mainly focused on discussion. Therefore, we plan to have only 2 talks every day.

This year we want to identify and discuss main problems and open questions in the realm of Skyrme type models. Therefore, while mornign talks will present recent results, afternoon talks will be devoted for a disussion related to an "open problem talk" selected by the speakers.

    Each visitor will share an office in the secure part of the institute.

    Coffee, Lunch, Refreshments

  • Coffee - one can enjoy good espresso (and other coffee varieties) at the Atom Bar, located at the main entrance of the Faculty.

    There is also a new! coffee espresso machine in the Theory Department's coffee room located in our section C-2.

  • Lunch - Atom Bar 13/15 PLN: soup, second course + salad + drink. There are also other student bars on Campus. So, feel free to explore. Unfortunately, there are no nice restaurants close to the Campus.

  • Dinners - TBA

  • Refreshments - TBA

  • Welcome party -TBA


  • Airport -> Krakow Glowny Train Station / City center.

    Balice Airport is connected with the Central Train Station (Krakow Glowny) by a direct train. Please, follow the signs at the Airport. Once you are at the Balice Train Station take any train. All trains go to Krakow Glowny - it is the only big station on the way. It takes approximately 17 min to get there and there is one train every 30 minutes. You can purchase your tickets from a self-service vending machine at the platform (cash/cards) or on board the train (cash - only polish zloty). It costs 8 PLN. See train time table.

  • Krakow Glowny Train Station -> Campus

    Once you arrive at Krakow Glowny leave the train station through the shopping center (Galeria Krakowska). To exit the shopping center, please follow the signs to Krakow Old Town. You will arrive at a rather big square with the shopping center in your back and an old train station building on the left (map). Please, continue straight (with the stream of people) until you see an underground passage (it leads to Planty - a green area around the Old Town). Don't take the passage but turn a bit left. There is a tram/bus stop. Take tram 52, direction "Czerwone Maki". The campus stop is "Norymberska" - just in front of "Kaufland" supermarket. The campus is behind the shopping center. A single tram ticket costs 3.80 PLN. You can buy it from a vending machine at some stops (cash/cards) or on board the tram (depending on the machine you pay by card or/and chash). See time table for tram 52.
