Line Integration Not Including The Pole Symbol
⨔ denotes line integration that does not include the pole.
U+2A14
⨔ (U+2A14) is a math symbol used to specify a line integral that avoids a pole. It helps clarify how the integral path treats singularities. Use it when your notation must be precise about excluding that point.
Line Integration Not Including The Pole Symbol Meaning
⨔ is the symbol named “LINE INTEGRATION NOT INCLUDING THE POLE” (U+2A14). In mathematical notation, it indicates a line integral taken along a curve where a pole is excluded. This distinguishes the integral from versions that might include the singular point or treat it differently. The emphasis is on the integration being performed while not including the pole in the domain of integration. If you are writing complex analysis, contour integral notes, or technical derivations, ⨔ can make your intent clearer to readers and reviewers, especially when discussing singularities and how paths are handled.
Common uses
- •Writing complex analysis notes where the contour integral must exclude a pole
- •Labeling integrals in derivations to clarify that the singular point is not included
- •Annotating math problem solutions involving singularities and path restrictions
- •Formatting documentation for symbolic computation or coursework notation
- •Providing precise notation in academic-style figures and equations
Examples
⨔ Line integration not including the pole
- ⨔⨔_C f(z) dz where C avoids the pole
- ⨔Compute ⨔_γ g(z) dz with γ not passing through the pole
- ⨔Let I = ⨔_Γ (1/(z-a)) dz, excluding z = a
- ⨔Evaluate ⨔_C h(z) dz for a contour that skirts the pole
- ⨔The integral is taken as ⨔ over a path that does not include the pole

FAQ
What does ⨔ mean in math?
⨔ denotes a line integration where the pole is not included in the integration domain.
Is ⨔ the same as a regular line integral?
No. A regular line integral may not specify how singular points are handled, while ⨔ explicitly indicates that the pole is excluded.
Where is ⨔ typically used?
It is commonly used in complex analysis and contour-integral contexts involving poles and carefully defined paths.
How do I find its Unicode and copy it?
The symbol is ⨔ with Unicode name “LINE INTEGRATION NOT INCLUDING THE POLE” and code point U+2A14.
