Half-hypermultiplets and incomplete/complete resolutions in F-theory
Naoto Kan, Shun'ya Mizoguchi, Taro Tani
We consider resolutions of codimension-two enhanced singularities from to and from to in six-dimensional F-theory, where a half-hypermultiplet arises for…

Non-Cartan Mordell-Weil lattices of rational elliptic surfaces and heterotic/F-theory compactifications
Shun'ya Mizoguchi, Taro Tani
The Mordell-Weil lattices (MW lattices) associated to rational elliptic surfaces are classified into 74 types. Among them, there are cases in which the MW lattice is none of the we…

Twisted boundary states and representation of generalized fusion algebra
Hiroshi Ishikawa, Taro Tani
The mutual consistency of boundary conditions twisted by an automorphism group G of the chiral algebra is studied for general modular invariants of rational conformal field theorie…
