The 2007 Abel Symposium came about on the college of Oslo in August 2007. The aim of the symposium used to be to compile mathematicians whose study efforts have resulted in fresh advances in algebraic geometry, algebraic K-theory, algebraic topology, and mathematical physics. a typical topic of this symposium was once the improvement of recent views and new structures with a express taste. because the lectures on the symposium and the papers of this quantity reveal, those views and structures have enabled a broadening of vistas, a synergy among once-differentiated matters, and suggestions to mathematical difficulties either outdated and new.

Lectures on Differential Geometry

This booklet is a translation of an authoritative introductory textual content in line with a lecture sequence added through the well known differential geometer, Professor S S Chern in Beijing college in 1980. the unique chinese language textual content, authored through Professor Chern and Professor Wei-Huan Chen, was once a different contribution to the math literature, combining simplicity and economic system of strategy with intensity of contents.

Projective Geometry

A research of linear order and continuity to provide a starting place for traditional genuine or complicated geometry.
