The Swiss Number Theory Days (NTD) is a conference series established in 2004 by Eva Bayer (EPFL Lausanne) and Gisbert Wüstholz (ETH Zürich).
The inaugural edition was held in Zürich in 2004, organized by Eva Bayer and Richard Pink. The conference subsequently alternated between Lausanne and Zürich. In 2017, the Number Theory Group at the University of Basel joined the initiative, and the conference now rotates among four locations: Basel, Brig, Lausanne, and Zürich.
The current organizers are Philipp Habegger (University of Basel), David Loeffler (Brig), Philippe Michel (EPFL Lausanne), and Özlem İmamoğlu (ETH Zürich).
Each edition of the NTD typically features four to six one-hour lectures covering a broad range of topics in number theory. The conference usually begins on Friday afternoon and concludes before noon on Saturday.
