March 29th - April 4th, 2026
“Jugendbildungszentrum Blossin e.V.” at Lake Wolzig
Mentored by Russell Avdek, Ipsita Datta, and Amanda Hirschi
Abstract
This workshop will focus on tools used to study moduli spaces of holomorphic curves, such as Kuranishi structures and obstruction bundle gluing. We will learn about the foundational theory and its underlying tools, as well as how to use them to prove theorems about contact and symplectic manifolds. The prerequisites are a strong understanding of differential topology and Fredholm operators, foundations of contact and symplectic manifolds, and basics of holomorphic curves.
About
This is the second instance of the European spin-off of the famous Kylerec workshop (see 2025 for the last year). The workshop is run by and for master students, PhD students, and young post-docs. The participants will spend a week by a small German lake giving talks under the guidance of our mentors. We strive to create an informal atmosphere and a safe space where the participants can enjoy the beauty of mathematics together and form new connections.
