Continuous-time research refers to the study of systems or processes that evolve continuously over time, as opposed to discrete-time systems that only change at specific points in time. This research area typically focuses on analyzing and modeling phenomena that can be described by differential equations or other continuous-time mathematical frameworks. Continuous-time research can be found in various fields such as physics, engineering, biology, and economics, among others. It often involves the use of advanced mathematical and computational techniques to understand and predict the behavior of continuous-time systems.
