343. Krzysztof Jan Nowak:
A counter-example concerning quantifier elimination in quasianalytic structures.

e-mail:

Submission: 2013, June 8.

Abstract:
This paper provides an example of a quasianalytic structure which does not admit quantifier elimination in the language of restricted quasianalytic functions augmented by the reciprocal function $1/x$. Our construction applies rectilinearization of terms as well as some theorems on power substitution for Denjoy--Carleman classes and on non-extendability of quasianalytic germs.

Mathematics Subject Classification (2010): 03C10, 26E10, 03C64.

Keywords and Phrases: quasianalytic structures, quantifier elimination, Denjoy--Carleman classes.
