چکیده
In the 80's D. Eisenbud and J. Harris considered the following problem: " What are the limits of Weierstrass points in families of curves degenerating to stable curves? " But for the case of stable curves of compact type, treated by them, this problem remained wide open since then. In the present article, we propose a concrete approach to this problem, and give a quite explicit solution for stable curves with just two irreducible components meeting at points in general position.

We investigate, in a certain decoupling limit, the effect of having a constant C– field on the M–theory five–brane using an open membrane probe. We define an open membrane metric for the five–brane that remains non–degenerate in the limit. The canonical quantisation of the open membrane boundary leads to a noncommutative loop space which is a functional analogue of the noncommutative geometry t...

متن کاملA ug 2 00 0 Jet Schemes of L . C . I . Canonical Singularities
Let X be a variety defined over an algebraically closed field k of characteristic zero. The mth jet scheme Xm of X is a scheme whose closed points over x ∈ X are morphisms OX,x −→ k[t]/(t ). When X is a smooth variety, this is an affine bundle over X, of dimension (n + 1) dim X. The space of arcs X∞ of X is the projective limit X∞ = proj limmXm. Our main result is a proof of the following theor...

We use Fermi coordinates to calculate the canonical partition function for an ideal gas in a circular geodesic orbit in Schwarzschild spacetime. To test the validity of the results we prove theorems for limiting cases. We recover the Newtonian gas law subject only to tidal forces in the Newtonian limit. Additionally we recover the special relativistic gas law as the radius of the orbit increase...
متن کامل0 M ay 2 00 6 Determinantal Characterization of Canonical Curves and Combinatorial Theta Identities
Canonical curves are characterized by the vanishing of combinatorial products of g + 1 determinants of the holomorphic abelian differentials. This also implies the characterization of canonical curves in terms of (g − 2)(g − 3)/2 theta identities and the explicit expression of the volume form on the moduli space of canonical curves induced by the Siegel metric. Together with the Mumford form, i...
