Workshop information:
This workshop aims at promoting work on Hilbert’s epsilon calculus in a number of relevant fields ranging from Philosophy and Mathematics to Linguistics and Informatics. The Epsilon and Tau operators were introduced by David Hilbert, inspired by Russell's Iota operator for definite descriptions, as binding operators that form terms from formulae. One of their main features is that substitution with Epsilon and Tau terms expresses quantification. This leads to a calculus which is a strict and conservative extension of First Order Predicate Logic. The calculus was developed for studying first order logic in view of the program of providing a rigorous foundation of mathematics via syntactic consistency proofs. The first relevant outcomes that certainly deserve a mention are the two "Epsilon Theorems" (similar to quantifiers elimination), the first correct proof of Herbrand’s theorem or the use of the Epsilon operator in Bourbaki’s Éléments de Mathématique. Nowadays the interest in the Epsilon substitution method has spread in a variety of fields: Mathematics, Logic, Philosophy, History of Mathematics, Linguistic, Type Theory, Computer science, Category Theory and others.

Submission
The workshop welcomes submissions of up to 4 (but not less than 2) pages. Usual spacing, font and margin should be used (single-spaced, 11pt or larger, and 1 inch margin on A4 or letter size paper). Abstracts should be submitted by April 1st, 2015 as pdf files through the EasyChair conference system ( https://easychair.org/conferences/?conf=epsilon2015). An indicative list of themes that are of particular interest to the conference are (non-exhaustive):

- History of Logic
- Philosophy
- Proof theory
- Model theory
- Category theory
- Type theory
- Quantification in Natural language
- Noun-Phrases Semantics
- Proof Assistants (e.g. Coq, Isabelle, ... )
- Other subnectors (e.g. Russell's iota, μ-operator, ... )
 
Reviewing:
Abstracts will be reviewed by members of the program committee, and, where appropriate, outside reviewers. The organizers will be responsible for making decisions partly in consultation with the program committee. Notifications will be made by May 1st, 2015. 

Post-Proceedings:
Selected papers from the workshop will appear as a special volume in Journal of Logics and their Applications
