A numerical criterion for generalised Monge-Ampère equations on projective manifolds [PDF]

open access: yesGeometric and Functional Analysis, 2020
We prove that generalised Monge-Ampère equations (a family of equations which includes the inverse Hessian equations like the J-equation, as well as the Monge-Ampère equation) on projective manifolds have smooth solutions if certain intersection numbers ...

Generation of Multi-Color Attosecond X-Ray Radiation Through Modulation Compression

open access: yes, 2011
In this paper, we propose a scheme to generate tunable multi-color attosecond coherent X-ray radiation for future light source applications. This scheme uses an energy chirped electron beam, a laser modulators, a laser chirper and two bunch compressors ...
