Transalpine Topology Tetrahedron

We are a vertex of the Transalpine Topology Tetrahedron (TTT). The TTT is a long running series of one-day topology gatherings held at Sheffield, Liverpool and Warwick, with an international node in Pavia. In September 2016, the TTT celebrated its 100th meeting.
Until November 2023, the TTT was known as the Transpennine Topology Triangle.

EL:ECTRIC (Ecstatic Lectures: Early Career Topology Researchers In Conference) is a conference whose aim is to bring together post-graduates and post-doctoral researchers in all areas of topology. 

Having previously been held at Imperial College, London under the name ECSTATIC, June 2017 saw the conference move to Sheffield, under the organisation of Gemma Halliwell and Dan Graves. View a list of participants (PDF, 46KB) and the abstracts (PDF, 155KB) for the talks.
