Self-introduction
In mathematical analysis, I study focusing on the initial boundary value problem of such partial differential equations as a wave equation and a heat equation. First, I am conducting mathematical analysis of a wave propagation phenomenon or a stationary state. I expect applying the result to the related problem including inverse problems formulated by the differential equation and analysis of phenomena of energy propagation.
