Discrepancies of non-$\Q$-Gorenstein varieties
We give an example of a non $\Q$-Gorenstein variety which is canonical but not klt, and whose canonical divisor has an irrational valuation. We also give an example of an irrational jumping number and we prove that there are no accumulation points for ...

Uniform stable radius, L\^e numbers and topological triviality for line singularities
Let $\{f_t\}$ be a family of complex polynomial functions with line singularities. We show that if $\{f_t\}$ has a uniform stable radius (for the corresponding Milnor fibrations), then the L\^e numbers of the functions $f_t$ are independent of $t$ for ...

Fundamental Domains in Lorentzian Geometry [PDF]
We consider discrete subgroups Gamma of the simply connected Lie group SU~(1,1), the universal cover of SU(1,1), of finite level, i.e. the subgroup intersects the centre of SU~(1,1) in a subgroup of finite index, this index is called the level of the ...

Testing Lipschitz non normally embedded complex spaces
We introduce a sectional criterion for testing if complex analytic germs $(X,0) \subset (\bC^n, 0)$ are Lipschitz non normally embedded.Comment: title changed; more introduction.

Quasi-log canonical pairs are Du Bois
We prove that every quasi-log canonical pair has only Du Bois singularities. Note that our arguments are free from the minimal model program.Comment: 6 pages, v2: very minor modifications, v3: add some explanations in the proof of Theorem 1.1.
