Euclidean path.

The difference between these distance measures is the axial constraints. With Euclidean distance, the distance between point A and point B is the length of a straight line drawn between these points. Manhattan distance instead seeks the shortest path that is parallel to the coordinate axes system, and that path may end up not being straight.The Lorentzian path integral is given by the transformation \(t\rightarrow Nt\) assuming N to be complex and aims to extend the Euclidean path integral formulation. The previous works [ 15 , 20 ] suggests the complex rotation \(t\rightarrow \tau e^{-i\alpha }\) and deforms of the real time contour to pass complex saddles.called worldine path integral formalism, or Euclidean worldine path integral formalism, when the proper time is taken to be purely imaginary as in Eq.(2) (see [48] for a recent review). Many years after Schwinger’s work, Affleck et al. reproduced Eq. (1) for a constant electric field using the Euclidean worldline path integral approach [31]. The difference between these distance measures is the axial constraints. With Euclidean distance, the distance between point A and point B is the length of a straight line drawn between these points. Manhattan distance instead seeks the shortest path that is parallel to the coordinate axes system, and that path may end up not being straight.

The great-circle distance, orthodromic distance, or spherical distance is the distance along a great circle . It is the shortest distance between two points on the surface of a sphere, measured along the surface of the sphere (as opposed to a straight line through the sphere's interior). The distance between two points in Euclidean space is the ...By extension, the action functional (12) is called the Euclidean action, and the path inte-gral (13) the Euclidean path integral.

The points, lines, angles are all the same and measured in the same way. What is different is the notion of distance. In Euclidean coordinate geometry distance is thought of as “the way the crow flies”. In taxicab geometry distance is thought of as the path a taxicab would take.
