Our goal is to establish a hidden regularity result for solutions of time fractional Petrovsky systems. The order \(\alpha \) of the Caputo fractional derivative belongs to the interval (1, 2). We achieve such result for a suitable class of weak solutions.

具有 Caputo 导数的双调和演化方程的迹规律

我们的目标是为时间分数彼得罗夫斯基系统的解建立一个隐藏的规律性结果。Caputo 分数阶导数的阶\(\alpha \)属于区间 (1, 2)。我们为一类合适的弱解实现了这样的结果。
