Two contributions to the arithmetic of varieties : R-equivalence and unramifi...
In this Ph.D. thesis, we investigate some arithmetic properties of algebraic varieties. The thesis consists of two parts, divided into eight chapters. The first part... -
Weak approximation and local-global principle for certain rationally connecte...
This thesis is concerned with the study of some arithmetic properties of certain algebraic varieties which are ``simplest'' in some geometric sense and which are...
