Download E-books On the Geometry of Some Special Projective Varieties (Lecture Notes of the Unione Matematica Italiana) PDF

By Francesco Russo

Providing an
introduction to either classical and smooth recommendations in projective
algebraic geometry, this monograph treats the geometrical homes of
varieties embedded in projective spaces, their secant and tangent lines,
the habit of tangent linear areas, the algebro-geometric and topological
obstructions to their embedding into smaller projective areas, and the
classification of extremal cases. It
also offers an answer of Hartshorne’s Conjecture on whole Intersections
for the category of quadratic manifolds and new brief proofs of formerly known
results, using the modern instruments of
Mori idea and of rationally attached manifolds.

The new method of a few of the
problems thought of may be resumed within the precept that, rather than learning a
special embedded manifold uniruled by way of strains, one passes to investigate the original
geometrical estate at the manifold of strains passing via a basic point
and inside the manifold. as soon as this embedded manifold, often of lower
codimension, is assessed, one attempts to reconstruct the unique manifold,
following a precept showing additionally in other
areas of geometry reminiscent of projective differential geometry or complex
geometry.

Download E-books Geometry of Vector Sheaves: An Axiomatic Approach to Differential Geometry Volume II: Geometry. Examples and Applications (Mathematics and Its Applications) (Volume 2) PDF

This two-volume monograph obtains primary notions and result of the normal differential geometry of soft (CInfinity) manifolds, with no utilizing differential calculus. right here, the sheaf-theoretic personality is emphasized. This has theoretical benefits equivalent to higher point of view, readability and unification, but in addition functional advantages starting from user-friendly particle physics, through gauge theories and theoretical cosmology (`differential spaces'), to non-linear Pdes (generalised functions). hence, extra common purposes, that are now not `smooth' within the classical feel, will be coped with. The treatise may additionally be construed as a brand new systematic endeavour to confront the ever-increasing inspiration that the `world round us is much from being delicate enough'.
Audience: This paintings is meant for postgraduate scholars and researchers whose paintings consists of differential geometry, international research, research on manifolds, algebraic topology, sheaf thought, cohomology, practical research or summary harmonic research.
