| Outline of Final Research Achievements |
Doi-Peliti formalism has been mainly used to analyze birth-death processes, which deals with discrete state variables. I investigated the mathematical meanings of the formalism, and it has been found that discrete variables can be connected to continuous variables and their differentials via the Doi-Peliti formalism. Using the findings, it is possible to derive dual processes from the original stochastic processes in systematic ways. Applying the duality concepts, dual processes for some stochastic differential equations and birth-death processes have been derived. In addition, using the dual processes, it is possible to construct rapid computational frameworks for time-series data analysis for the original stochastic processes.
