Regularity bounds for a Gevrey criterion in a kernel-based regularization of the Cauchy problem of elliptic equations

This Note derives regularity bounds for a Gevrey criterion when the Cauchy problem of elliptic equations is solved by regularization. When utilizing the regularization, one knows that checking such criterion is basically problematic, albeit its importance to engineering circumstances. Therefore, coping with that impediment helps us improve the use of some regularization methods in real-world applications. This work also considers the presence of the power-law nonlinearities.
