## geodesic curvature

[¦jē·ə¦des·ik ′kərv·ə·chər]
(mathematics)
For a point on a curve lying on a surface, the curvature of the orthogonal projection of the curve onto the tangent plane to the surface at the point; it measures the departure of the curve from a geodesic. Also known as tangential curvature.

In other words, its acceleration is normal to the manifold so that the geodesic curvature is zero along the geodesic, and thus the two-point boundary value problem (TPBVP) arises from geodesic differential equations on Riemannian manifold.
