Spectral involutions on rational elliptic surfaces
Ron Donagi, Burt Ovrut, Tony Pantev +1
In this paper we describe a four dimensional family of special rational elliptic surfaces admitting an involution with isolated fixed points. For each surface in this family we cal…

Nonabelian mixed Hodge structures
Ludmil Katzarkov, Tony Pantev, Carlos Simpson
We propose a definition of ``nonabelian mixed Hodge structure'' together with a construction associating to a smooth projective variety and to a nonabelian mixed Hodge structur…

Standard Model Vacua in Heterotic M-Theory
Ron Donagi, Burt A. Ovrut, Tony Pantev +1
We present a class of N=1 supersymmetric ``standard'' models of particle physics, derived directly from heterotic M-theory, that contain three families of chiral quarks and leptons…
