J. - L.关于非自治形式控制方程的极大正则性的Lions问题
J.-L. Lions' Problem Concerning Maximal Regularity of Equations Governed by Non-Autonomous Forms
摘要：
一个老问题，由于J。L.狮子回到20世纪60年代问抽象柯西问题相关的非自治形式是否有最大的规律性，如果时间依赖性只是假设是连续的，甚至是可测量的。我们给出了一个否定的回答这个问题，并讨论了积极的结果所需的最小正则性。
英文摘要：
An old problem due to J.-L. Lions going back to the 1960s asks whether the abstract Cauchy problem associated to non-autonomous forms has maximal regularity if the time dependence is merely assumed to be continuous or even measurable. We give a negative answer to this question and discuss the minimal regularity needed for positive results.
