Line Integration With Rectangular Path Around Pole Symbol
⨒ represents line integration with a rectangular contour around a pole in math notation.
U+2A12
⨒ is a mathematical symbol used in contexts involving contour or path integrals. Its official name describes a rectangular path taken around a pole. This page helps you copy the character and understand how it’s typically referenced in notation.
Line Integration With Rectangular Path Around Pole Symbol Meaning
⨒ (Unicode U+2A12) stands for “LINE INTEGRATION WITH RECTANGULAR PATH AROUND POLE.” In math and physics-style notation, it signals that an integral is evaluated along a rectangular contour chosen specifically to enclose a singularity (a pole). The rectangular shape matters because it reflects a particular integration path used in a derivation or evaluation. When writing equations, ⨒ is often paired with integral symbols and expressions indicating the integrand and the contour (e.g., specifying that the path loops around the pole). Use it when you want the contour-path aspect (rectangular around a pole) to be explicit rather than implied.
Common uses
- •Writing contour integral notation in complex analysis where a rectangular contour encloses a pole
- •Annotating worked solutions that emphasize the chosen integration path shape (rectangular) around a singularity
- •Documenting formulas in math/physics notes where contour choice is part of the method
- •Labeling variables or steps in derivations that reference “rectangular path” assumptions
- •Creating lecture slides or technical diagrams that distinguish rectangular contour integrals from other shapes
Examples
