-designs admitting a flag-transitive automorphism group with socle
Hongxue Liang, Mario Galici, Zhihui Liu +3
-designs admitting a flag-transitive automorphism group with socle , where , are investigated in both the point-primitive and point-imprimitive case…
K-polystability of Fano 4-folds with large Lefschetz defect
Eleonora A. Romano, Saverio A. Secci
In this paper, we investigate K-polystability on smooth complex Fano 4-folds with Lefschetz defect at least 2, focusing on the case of Lefschetz defect 3 and on Casagrande-Druel Fa…
Chow quotients of -actions
Gianluca Occhetta, Eleonora A. Romano, Luis E. Solá Conde +1
Given an action of the one-dimensional torus on a projective variety, the associated Chow quotient arises as a natural parameter space of invariant -cycles, which dominates the…
Mori Dream Bonds and -actions
Lorenzo Barban, Eleonora A. Romano, Luis E. Solá Conde +1
We construct a correspondence between Mori dream regions arising from small modifications of normal projective varieties and -actions on polarized pairs which are bor…
Geometric realizations of birational transformations via -actions
Gianluca Occhetta, Eleonora A. Romano, Luis E. Solá Conde +1
In this paper we study varieties admitting torus actions as geometric realizations of birational transformations. We present an explicit construction of these geometric realization…
Fano manifolds with Lefschetz defect 3
C. Casagrande, E. A. Romano, S. A. Secci
Let X be a smooth, complex Fano variety, and delta(X) its Lefschetz defect. It is known that if delta(X) is at least 4, then X is isomorphic to a product SxT, where dim T=dim X-2.…
