> Title:
> The epsilon calculus with equality predicate and Herbrand complexity
> 
> Abstract:
> Hilbert's epsilon-calculus is based on an extension of the language of
> predicate logic by a term-forming operator $\varepsilon$ [1].  Two
> fundamental results about the epsilon-calculus, the first and second
> epsilon theorem, play a role similar to that which the cut-elimination
> theorem plays in sequent calculus.  In particular, Herbrand's Theorem
> is a consequence of the epsilon theorems.  Moser and Zach study the
> epsilon theorems and the complexity of the elimination procedure
> underlying their proof, as well as the length of Herbrand disjunctions
> of existential theorems obtained by this elimination procedure [2].
> We extend their results to epsilon-calculus with equality predicate.
> This is joint work with Georg Moser.
