We use path integrals to calculate hedge parameters and efficacy of hedging in a quantum field theory generalization of the Heath, Jarrow, and Morton [Robert Jarrow, David Heath, and Andrew Morton, Econometrica 60, 77 (1992)] term structure model, which parsimoniously describes the evolution of imperfectly correlated forward rates. We calculate, within the model specification, the effectiveness...

This article revisits the Diffusion Operator Integral (DOI) variance reduction technique originally proposed in Heath and Platen (2002) extends its theoretical concept to pricing of America...

We describe a family of graphs with queue-number at most 4 but unbounded stack-number. This resolves open problems Heath, Leighton and Rosenberg (1992) Blankenship Oporowski (1999).

Globally, species extinctions are driven by multiple interacting factors including altered fire regimes and introduced predators. In flammable ecosystems, there is great potential to use for animal conservation, however most fire-based conservation strategies do not explicitly consider factors. this study, we sought understand the interrelationships between endangered heath mouse Pseudomys shor...
