U+2A14 "⨔" Line Integration Not Including the Pole Unicode Character

U+2A14 "⨔" Line Integration Not Including the Pole is a mathematical symbol classified under the Supplemental Mathematical Operators block, designed for use in complex analysis and contour integration notation. It specifically denotes a path integral around a closed curve that deliberately excludes a singular point of the integrand, such as a pole, thereby indicating that the integration contour avoids the singularity. This symbol is often employed in contexts like Cauchy's integral theorem or residue calculations where the pole lies inside the contour but the integration path is taken to exclude it, typically by routing the contour around the pole through a small indentation. By providing a precise notation for this common operation, it helps clarify that the integral's value does not include the residue contribution from the excluded pole.
