A NOTE ON AXIOMS FOR INFINITE-GENERIC STRUCTURES (2008)

Angus Macintyre

In this note we give some natural examples of theories T in countable logics L such that the class GT of infinite-generic structures for T is not axiomatizable by a single sentence of LW1> w. The...

FREE ABELIAN LATTICE-ORDERED GROUPS (2008)

Angus Macintyre, Françoise Point

Abstract. Let n be a positive integer and F Aℓ(n) be the free abelian latticeordered group on n generators. We prove that F Aℓ(m) and F Aℓ(n) do not satisfy the same first-order sentences in...

Abstract (2008)

Angus Macintyre, Eduardo D. Sontag

This paper deals with analog circuits. It establishes the finiteness of VC dimension, teaching dimension, and several other measures of sample complexity which arise in learning theory. It also shows...

A Failure of Quantifier Elimination (2007)

Angus Macintyre, David Marker, Let L

uld actually eliminate quantifiers in the language L an [ flogg [ fx q : q 2 Qg. Here we show that although exp and log are interdefinable, log is essential for quantifer elimination. Theorem. Let...

A Generalization of Wilkie's Theorem of the Complement, and an Application to Pfaffian Closure (2007)

Marek Karpinski, Angus Macintyre, Marek Karpinski (bonn, Angus Macintyre (edinburgh

Using a modification of Wilkie's recent proof of o-minimality for Pfaffian functions, we give an invariant characterization of o-minimal expansions of IR. We apply this to construct the Pfaffian...

Logarithmic-exponential series (2007)

Angus Macintyre, David Marker

Abstract. We extend the field of Laurent series over the reals in a canonical way to an ordered differential field of "LE-series " (logarithmic-exponential series), which is...
