AI总结:

该研究借助热Riesz位势建立含测度数据与仅可测系数的混合局部-非局部抛物方程弱解的逐点与振荡估计,通过证明带最优L^q-Tail的局部Hölder估计拓展以往结果,且结论适用于SOLA,捕捉了双相抛物方程的局部与非局部特征。

摘要:

我们借助热Riesz位势,建立了含测度数据与仅可测系数的混合局部-非局部抛物方程弱解的一类逐点估计。这类估计分别有效界定了弱解的大小与振荡幅度。证明的关键在于为对应齐次问题的弱解建立了带最优$L^q$-Tail的新局部Hölder估计,显著拓展了以往工作中的$L^\text{∞}$-Tail结果。值得一提的是,我们的主要结果既捕捉了双相抛物方程的局部与非局部特征,更重要的是对SOLA(逼近极限解)依然成立。

英文摘要:

We establish a class of pointwise estimates for weak solutions to mixed local and nonlocal parabolic equations involving measure data and merely measurable coefficients via caloric Riesz potentials. Such estimates effectively bound the sizes and oscillations of weak solutions, respectively. The proof relies on demonstrating a new local Hölder estimate with an optimal $L^q$-Tail for weak solutions to the corresponding homogeneous problem, which remarkably extends the $L^\infty$-Tail in previous work. It is worth mentioning that our main results capture both local and nonlocal features of the double phase parabolic equations and, more importantly, remain valid for SOLA (Solutions Obtained by Limit of Approximations).
