The Artin conjecture for Q-algebras.
Ronan Quarez (1997)
Revista Matemática de la Universidad Complutense de Madrid
Similarity:
We give a simplification, in the case of Q-algebras, of the proof of Artin's Conjecture, which says that a regular morphism between Noetherian rings is the inductive limit of smooth morphisms of finite type.
Classification of obstructions for separation of semialgebraic sets in dimension 3.
F. Acquistapace, F. Broglia, C. Andradas (1997)
Revista Matemática de la Universidad Complutense de Madrid
Similarity:
Applying general results on separation of semialgebraic sets and spaces of orderings, we produce a catalogue of all possible geometric obstructions for separation of 3-dimensional semialgebraic sets and give some hints on how separation can be made decidable.
Levelled O-minimal structures.
David Marker, Chris Miller (1997)
Revista Matemática de la Universidad Complutense de Madrid
Similarity:
We introduce the notion of leveled structure and show that every structure elementarily equivalent to the real expo field expanded by all restricted analytic functions is leveled.

In the paper ordinary neutral differential equations with ?maxima? are considered. Sufficient conditions for oscillation of all solutions are obtained.
