The paper investigates general properties of the power series over a non- Archimedean ordered field, extending to the set of algebraic power series the intermediate value theorem and Rolle's theorem and proving that an algebraic series attains its ma

In the present paper we investigate the convergence of a double series over a complete non-Archimedean field and prove that, while the proofs are somewhat different, the Archimedean results hold true.

In two previous papers, we defined, for every projective, 0-dimensional, reduced scheme X, a set of numerical sequences, which turns out to be a refinement of the Hilbert function of X. Here, we extend that definition to the case of a scheme X not ne

We study the relation of continuous reducibility, or Wadge reducibility, between subsets of an affine variety. We show that on any curve the relation of continuous reducibility is a bqo, though it may have large finite antichains. We determine the Wa

This paper proves that all power series over a maximal ordered Cauchy complete non-Archimedean field satisfy the intermediate value theorem on every closed interval. Hensel's lemma for restricted power series is the main tool of the proof.

The paper proves an intermediate value theorem for polynomials and power series over a valued field with an additive divisible valuation group and infinite residue field. A deeper description of the behavior of the valuation for power series is obtai

In this paper we introduce the concept of inessential element of a standard basis of I, where I is any homogeneous ideal of a polynomial ring. An inessential element is, roughly speaking, a form of the basis whose omission produces an ideal having th

Campanella's refinements of Dubreil's theorem are sharp upper and lower bounds, formulated in postulational terms, for the number of forms of any given degree in the standard bases of 2-codimensional perfect homogeneous polynomial ideals. This note c
