Stable rationality of higher dimensional conic bundles
Hamid Abban, Takuzo Okada
We prove that a very general nonsingular conic bundle embedded in a projective vector bundle of rank over is not stably ration…
Stable rationality of orbifold Fano threefold hypersurfaces
Takuzo Okada
We determine the rationality of very general quasismooth Fano 3-fold weighted hypersurfaces completely and determine the stable rationality of them except for cubic 3-folds. More p…
Stable rationality of cyclic covers of projective spaces
Takuzo Okada
The main aim of this paper is to show that a cyclic cover of branched along a very general divisor of degree is not stably rational provided that and $…
Alpha invariants of birationally rigid Fano threefolds
In-Kyun Kim, Takuzo Okada, Joonyeong Won
We compute global log canonical thresholds, or equivalently alpha invariants, of birationally rigid orbifold Fano threefolds embedded in weighted projective spaces as codimension t…
