Rationality of the moduli spaces of Eisenstein K3 surfaces
Shouhei Ma, Hisanori Ohashi, Shingo Taki
K3 surfaces with non-symplectic symmetry of order 3 are classified by open sets of twenty-four complex ball quotients associated to Eisenstein lattices. We show that twenty-two of…
The rationality of the moduli spaces of trigonal curves
Shouhei Ma
The moduli spaces of trigonal curves are proven to be rational when the genus is divisible by 4.
Rationality of the moduli spaces of 2-elementary K3 surfaces II
Shouhei Ma
We prove that the moduli spaces of K3 surfaces with non-symplectic involution are rational for four deformation types. With the previous results, this establishes the rationality o…
Rationality of fields of invariants for some representations of SL(2)\timesSL(2)
Shouhei Ma
We prove that the quotient by SL(2)\timesSL(2) of the space of bidegree (a, b) curves on P^1\timesP^1 is rational when ab is even and a\not=b.
