Effective Non-vanishing of Asymptotic Adjoint Syzygies
Effective Non-vanishing Asymptotic Adjoint Syzygies Algebraic Geometry
2012/4/17
The purpose of this paper is to establish an effective non-vanishing theorem for the syzygies of an adjoint-type line bundle on a smooth variety, as the positivity of the embedding increases. Our purp...
Extension theorems, Non-vanishing and the existence of good minimal models
Extension theorems Non-vanishing existence of good minimal models
2011/1/17
We prove an extension theorem for effective plt pairs (X, S+B) of non-negative Kodaira dimension (KX +S+B) ≥ 0.The main new ingredient is a refinement of the Ohsawa-Takegoshi
L2 extension theorem in...
Fixation in Evolutionary Games under Non-Vanishing Selection
Non-Vanishing Selection evolutionary game
2010/4/7
One of the most striking effect of fluctuations in evolutionary game theory is the possibility for mutants to fixate (take over) an entire population. Here, we formulate a WKB (Wentzel-Kramers-Brillou...
