Relative semiampleness in mixed characteristic
Jakub Witaszek
We show that a nef line bundle on a proper scheme over an excellent base is semiample if and only if it is semiample after restricting to characteristic zero and to positive charac…
The Du Bois complex of a hypersurface and the minimal exponent
Mircea Mustata, Sebastian Olano, Mihnea Popa +1
We study the Du Bois complex of a hypersurface in a smooth complex algebraic variety in terms its minimal exponent . The latter is an in…
Resolution and alteration with ample exceptional divisor
János Kollár, Jakub Witaszek
In this short note we explain how to construct resolutions or regular alterations admitting an ample exceptional divisor, assuming the existence of projective resolutions or regula…
Global Frobenius Liftability II: Surfaces and Fano Threefolds
Piotr Achinger, Jakub Witaszek, Maciej Zdanowicz
In this article, a sequel to "Global Frobenius Liftability I" (math:1708:03777v2), we continue the development of a comprehensive theory of Frobenius liftings modulo . We stud…
