ManyVal 2015

Les Diablerets • Switzerland • 11 - 13 December 2015

Update: Some photos from the meeting can be found here.

ManyVal is a series of international workshops on the logical and algebraic aspects of many-valued reasoning. The aim of the workshops is to gather both established and young researchers sharing an interest for a specific topic. Accordingly, each edition has a sharp focus. The attendance is limited in order to facilitate close and informal interaction. There are no parallel sessions. Contributed talks are allocated ample time.

ManyVal 2015 will focus on modal and first-order many-valued logics.

Important Dates

Deadline for abstracts:
25th September 2015
Notification of acceptance:

Registration deadline:
10th November 2015
Arrival day (no talks):

The workshop will take place at Hotel Les Sources , Les Diablerets , Switzerland.

The nearest airport is Geneva, but there are also good train connections from Basel, Zurich and Bern. All train connections go via Aigles, where you have to change trains.

To reach Hotel Les Sources from the train station, take the road and then the path following the river upwards (you will have to cross the river). After passing the large Hotel Victoria building, Hotel Les Sources is on your right. The walk should take about 10 minutes.

Call for Abstracts

Participants who wish to give a talk should submit an extended abstract (max. 2 pages written in plain LaTeX) before 25th September 2015 via the Easychair website .


Full board accommodation at Hotel Les Sources, including all meals from dinner on December 10th to lunch on December 13th, will cost CHF 483 for a single room or CHF 411 for a shared double room.

Each participant should register via the workshop webpage before 10th November 2015, and pay their own bill at the hotel upon departure. If you are interested in taking part in ManyVal 2015, please fill in the registration form .
