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]. Approach: Since the Euclidean distance is nothing but the straight line distance between two given points, therefore the distance formula derived from the Pythagorean theorem can be used. The formula for distance between two points (x1, y1) and (x2, y2) is We can get the above formula by simply applying the Pythagoras theoremThe 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.Definition 1.2.Given an undirected graph = ( , ), the shortest path metric of the graph is de ned as follows. The set of points is the set of vertices , and for any , ∈ , the distance ( , ) is the length of the shortest path connecting and in the graph. 1Euclidean space.

This chapter focuses on Quantum Mechanics and Quantum Field Theory in a euclidean formulation. This means that, in general, it discusses the matrix elements of the quantum statistical operator e βH (the density matrix at thermal equilibrium), where H is the hamiltonian and β is the inverse temperature. The Euclidean path integral is compared to the thermal (canonical) partition function in curved static space-times. It is shown that if spatial sections are non-compact and there is no Killing horizon, the logarithms of these two quantities differ only by a term proportional to the inverse temperature, that arises from the vacuum energy. When spatial sections are bordered by Killing horizons ...
