A mirror theorem for partial flag bundles
Ionut Ciocan-Fontanine, Yuki Koto
We construct a family of points on the Lagrangian cone of a partial flag bundle associated to a (possibly non-split) vector bundle from any Weyl-invariant -function of a prequot…

Quantum cohomology of projective bundles
Hiroshi Iritani, Yuki Koto
We construct an I-function of the projective bundle P(V) associated with a not necessarily split vector bundle V\to B as a Fourier transform of the S^1-equivariant J-function of th…

Normal stable degenerations of Noether-Horikawa surfaces
Hiroto Akaike, Makoto Enokizono, Masafumi Hattori +1
We classify all normal stable Horikawa surfaces with only -Gorenstein smoothable log canonical singularities. Furthermore, we provide a criterion for their global $\mat…
