Lim-stable singularities are of log canonical type
Lim-stable singularities are of log canonical type
Let be a normal local domain essentially of finite type over a field of characteristic zero. Suppose that is lim-stable, for example, semistable. Lim-stability conjecture. Then is of log canonical type; in particular, is pseudo-log canonical. The claim strengthens the expectation that lim-stable singularities in characteristic zero are pseudo-log canonical without assuming numerical -Gorensteinness. Its status is not resolved in the supplied text.
