Blow ups of projective spaces and Mori dream spaces

Abstruct: We consider blow ups of projective spaces at a variety and give examples of non Mori dream space over an arbitrary field. As an application, we give a negative answer to Cowsik's problem, which is a variation of Hilbert's 14th problem. This is a joint work with Hiromu Tanaka.
