Valuation Theory. Part I
In the article we introduce a valuation function over a field [1]. Ring of non negative elements and its ideal of positive elements have been also defined.
Valuations and asymptotic invariants for sequences of ideals
We study asymptotic jumping numbers for graded sequences of ideals, and show that every such invariant is computed by a suitable real valuation of the function field. We conjecture that every valuation that computes an asymptotic jumping number is necessarily quasi-monomial. This conjecture holds in dimension two. In general, we reduce it to the case of affine space and to graded sequences of valuation ideals. Along the way, we study the structure of a suitable valuation space.
