On topologically trivial automorphisms of compact Kähler manifolds and algebraic surfaces
Fabrizio Catanese, Wenfei Liu
In this paper, we investigate automorphisms of compact Kähler manifolds with different levels of topological triviality. In particular, we provide several examples of smooth comple…
Log surfaces of Picard rank one from four lines in the plane
Valery Alexeev, Wenfei Liu
We derive simple formulas for the basic numerical invariants of a singular surface with Picard number one obtained by blowups and contractions of the four-line configuration in the…
On numerical nonvanishing for generalized log canonical pairs
Jingjun Han, Wenfei Liu
The nonvanishing conjecture for projective log canonical pairs plays a key role in the minimal model program of higher dimensional algebraic geometry. The numerical nonvanishing co…
Simple connectedness of Fano log pairs with semi-log canonical singularities
Osamu Fujino, Wenfei Liu
We show that any union of slc strata of a Fano log pair with semi-log canonical singularities is simply connected. In particular, Fano log pairs with semi-log canonical singulariti…
Open surfaces of small volume
Valery Alexeev, Wenfei Liu
We construct a surface with log terminal singularities and ample canonical class that has and a log canonical pair with a nonempty reduced divisor and…
Automorphisms of surfaces of general type with q>=2 acting trivially in cohomology
Jin-Xing Cai, Wenfei Liu, Lei Zhang
A compact complex manifold X is said to be rationally cohomologically rigidified if its automorphism group Aut(X) acts faithfully on the cohomology ring H*(X,Q). In this note, we p…
