In this paper, we establish strong backward uniqueness for solutions to sublinear parabolic equations of the type (1.1). The proof of our main result Theorem 1.3 is achieved by means of a new Carleman estimate and a Weiss type monotonicity formula that are tailored for such parabolic sublinear operators.

次线性抛物方程的强向后唯一性

在本文中，我们为类型为（1.1）的亚线性抛物方程建立了强大的后向唯一性。我们的主要结果的证明定理1.3是通过新的Carleman估计和针对此类抛物线亚线性算子量身定制的Weiss型单调性公式实现的。
