报告题目:Transition path II: Optimal control and rare event simulations
发言提纲:Conformational transitions are important in biochemical reactions, which are usually described by irreversible drift-diffusion processes. We will first summarize several reversibility criteria. Then we propose two upwind finite volume schemes for the Fokker-Planck equation with or without the information of the invariant measure. Both two schemes enjoy stochastic Q-matrix structures and can be decomposed as a gradient flow part and a Hamiltonian flow part, which enable us to prove unconditional stability, ergodicity and error estimates.
