The Newton tree: geometric interpretation and applications to the motivic zeta function and the log canonical threshold
Let I be an arbitrary ideal in C[[x,y]]. We use the Newton algorithm to
compute by induction the motivic zeta function of the ideal, yielding only few
poles, associated to the faces of the successive Newton polygons. We associate
a minimal Newton tree to I, related to using good coordinates in the Newton
algorithm, and show that it has a conceptual geometric interpretation in terms
of the log canonical model of I. We also compute the log canonical threshold
from a Newton polygon and strengthen Corti's inequalities.Comment: 32 page
Invariants of plane curve singularities and Newton diagrams
We present an intersection-theoretical approach to the invariants of plane
curve singularities , , related by the Milnor formula
. Using Newton transformations we give formulae for ,
, which imply planar versions of well-known theorems on
nondegenerate singularities
Multivariable Hodge theoretical invariants of germs of plane curves
We describe methods for calculation of polytopes of quasiadjunction for plane
curve singularities which are invariants giving a Hodge theoretical refinement
of the zero sets of multivariable Alexander polynomials. In particular we
identify some hyperplanes on which all polynomials in multivariable Bernstein
ideal vanish
Adapting the Core Language Engine to French and Spanish
We describe how substantial domain-independent language-processing systems
for French and Spanish were quickly developed by manually adapting an existing
English-language system, the SRI Core Language Engine. We explain the
adaptation process in detail, and argue that it provides a fairly general
recipe for converting a grammar-based system for English into a corresponding
one for a Romance language.Comment: 9 pages, aclap.sty; to appear in NLP+IA 96; see also
