Transformation Mechanism of a Fault and Its Associated Microstructures in Low-Porosity Rocks: A Case Study of the Tanan Depression in the Hailar-Tamtsag Basin

Journal of Marine Science and Engineering, 2019
Faults have complex internal structures, which can be divided into the fault core and the damaged zone. During the fault formation process, the damaged zone will develop a large number of fractures cross cutting the adjacent host rocks, where the size ...

Liberté et accumulation

Documenta Mathematica, 2017
Le principe de Batyrev et Manin et ses variantes donnent une interprétation conjecturale précise pour le terme dominant du nombre de points de hauteur bornée d'une variété algébrique dont l'opposé du faisceau canonique est suffisamment positif. Comme l'a clairement montré le contre-exemple de Batyrev et Tschinkel la mise en œuvre de ce principe ...
