Complex Geometry and Supergeometry
Eric D'Hoker, D. H. Phong
Complex geometry and supergeometry are closely entertwined in superstring perturbation theory, since perturbative superstring amplitudes are formulated in terms of supergeometry, a…
The Monge-Ampère operator and geodesics in the space of Kähler potentials
D. H. Phong, Jacob Sturm
It is shown that geodesics in the space of Kähler potentials can be uniformly approximated by geodesics in the spaces of Bergman metrics. Two important tools in the proof are the T…
Two-loop superstrings and S-duality
Eric D'Hoker, Michael Gutperle, D. H. Phong
The two-loop contribution to the Type IIB low energy effective action term , predicted by SL(2,Z) duality, is compared with that of the two-loop 4-point function derived r…
Two-Loop Superstrings VI: Non-Renormalization Theorems and the 4-Point Function
Eric D'Hoker, D. H. Phong
The N-point amplitudes for the Type II and Heterotic superstrings at two-loop order and for massless NS bosons are evaluated explicitly from first principles, using the…
