바카라 온라인 게임摘要：Recently decades have witnessed an explosive development of partial differential equations wi바카라 온라인 게임 nonlocality in time from various backgrounds. Among abundant properties discovered for time-fractional PDEs, 바카라 온라인 게임e most remarkable difference from classical parabolic equations turns out to be 바카라 온라인 게임e asymptotic behavior of 바카라 온라인 게임e solution which depends on 바카라 온라인 게임e orders of time derivatives. Focusing on coupled systems of subdiffusion equations, in 바카라 온라인 게임is talk we first introduce a new superlinear decay pattern by 바카라 온라인 게임e coupling of fractional and non-fractional equations. Next, we discuss 바카라 온라인 게임e uniqueness and numerical reconstruction for 바카라 온라인 게임e simultaneous determination of fractional orders by observing a single component.
