Unramified cohomology, integral coniveau filtration and Griffiths group
Shouhei Ma
We prove that the degree k unramified cohomology with torsion coefficients of a smooth complex projective variety X with small CH_0(X) has a filtration of length [k/2], whose first…

Algebra of Borcherds products
Shouhei Ma
Borcherds lift for an even lattice of signature (p,q) is a lifting from weakly holomorphic modular forms of weight (p-q)/2 for the Weil representation. We introduce a new product o…

Kodaira dimension of universal holomorphic symplectic varieties
Shouhei Ma
We prove that the Kodaira dimension of the n-fold universal family of lattice-polarized holomorphic symplectic varieties with dominant and generically finite period map stabilizes…
