Statistical projections for dimensional reduction and for multiscale sampling

I will present methods for reducing the complexity of multiscale computation based on formalisms from irreversible statistical mechanics. I will explain the connection between statistical mechanics and computation. In the time dependent case I will explain how the formalism can be tamed by approximation, in particular in the case of long memory, with applications in fluid mechanics. In the sampling problem I will present a chain-free Monte Carlo formalism, with applications to spin glasses.
