An Infinitesimal Noether-lefschetz Theorem for Chow Groups
Let X be a smooth, complex projective variety, and Y be a very general, sufficiently ample hypersurface in X. A conjecture of M. V. Nori states that the natural restriction map CH(X)Q → CH(Y )Q is an isomorphism for all p < dimY and an injection for p = dimY . This is the generalized Noether-Lefschetz conjecture. We prove an infinitesimal version of this conjecture.
متن کاملInfinitesimal Hartman-Grobman Theorem in Dimension Three.
In this paper we give the main ideas to show that a real analytic vector field in R3 with a singular point at the origin is locally topologically equivalent to its principal part defined through Newton polyhedra under non-degeneracy conditions.
متن کاملInfinitesimal Torelli Theorem for Surfaces with C
In the present paper, we will prove the infinitesimal Torelli theorem for general minimal complex surfaces X’s with c1 = 3, χ(O) = 2, and Tors(X) ≃ Z/3, where c1, χ(O), and Tors(X) are the first Chern class, the Euler characteristic of the structure sheaf, and the torsion part of the Picard group of X, respectively. We will also show that all surfaces with the invariants as above are deformatio...
متن کاملJ. M. Rattray
The death of Dr. John Moysey Rattray on November 4th, aged 65, causes a gap among our older medical colleagues ; for although he had retired from his practice at Frome, he retained his untiring interest in all that concerned the profession he had served so well, and that cheerful, bright, conversational power that rendered him always a delightful companion, and made one forget that he was no lo...
متن کاملDiffusion processes via parabolic equations: an infinitesimal approach to Lindeberg's limit theorem
We approach infinitesimal diffusion processes via a linkage to the diffusion equation. By this we obtain Lindeberg’s limit theorem and a Lindeberg type limit theorem for diffusion processes by an application of the underspill principle. 2000 Mathematics Subject Classification 26E35 (primary); 60F05, 60J60, 35K99, 03H05 (secondary)
