Q-complements on log surfaces

I. Yu. Fedorov, S. A. Kudryavtsev

In this paper the log surfaces without $\QQ$-complement are classified. In particular, they are non-rational always. This result takes off the restriction in the theory of compleme…

Divisorial contractions to some Gorenstein singularities

I. Yu. Fedorov

Divisorial contractions to singularities, defined by equations $x y + z^{n} + u^{n} = 0$ $n \geq 3$ and $x y + z^{3} + u^{4} = 0$ are classified.
