In this paper, we show that these functions are able to detect the positions and orientations of all higher order jump discontinuities which lie along circles on the 2-sphere. Specifically, we prove upper and lower estimates for the magnitude of the corresponding inner products when the analysis function is concentrated in the neighborhood of such a singularity. 2023-04-05T09:30:43Z 2023-04-05T09:30:43Z 2023 Book https://link.springer.com/article/10.1007/s13137-023-00217-w https://dlib.phenikaa-uni.edu.vn/handle/PNK/7599 en application/pdf Springer
