Abstract:

The purpose of this paper is to analyze the time-fractional non-autonomous evolution equation which is associated with a family of linear operators depending on the time parameter $t$. Using the representation theorem by Lions, we obtain the sufficient conditions for well-posedness of the weak solution. Based on an orthogonal projection, we establish the invariance criterion for the weak solution of the time-fractional evolution equation. The operators of investigated equations are time-dependent.

Key words: Well-posedness, Caputo fractional derivative, Weak solution, Non-autonomous evolution equation
