Line 28:

| In [[Kaluza–Klein theory]], a unification of [[general relativity]] and [[electromagnetism]], the five-fimensional Kaluza–Klein–Riemann curvature tensor (or Kaluza–Klein–Riemann–Christoffel curvature tensor) is the generalization of the four-dimensional [[Riemann curvature tensor]] (or Riemann–Christoffel curvature tensor).

Line 35:

| The [[Ising model]] is a prototypical model in [[statistical physics]]. The model consists of discrete variables that represent magnetic dipole moments of atomic "spins" that can be in one of two states (+1 or −1). The spins are arranged in a graph, usually a lattice (where the local structure repeats periodically in all directions), allowing each spin to interact with its neighbors.

Line 77:

| In [[differential geometry]] and in particular [[Yang–Mills theory]], Uhlenbeck's singularity theorem is a result allowing the removal of a [[Singularity (mathematics)|singularity]] of a [[Four-dimensional Yang–Mills theory|four-dimensional Yang–Mills]] field with finite energy using gauge. It states as a consequence that Yang–Mills fields with finite energy on flat [[euclidean space]] arise from Yang–Mills fields on the curved [[sphere]], its [[one-point compactification]].

| [[Conformal rotation vector]]

| The conformal rotation vector, whose coordinates are also known as modified Rodrigues parameters or Wiener–Milenkovic parameters, is a three-dimensional [[Quaternion#Scalar and vector parts|vector]] representing a [[3D rotation group|three-dimensional rotation]] or [[orientation (geometry)|orientation]]. It is the [[stereographic projection]] of a [[versor]] ([[quaternions and spatial rotation|unit quaternion]]) onto the [[Quaternion#Definition|pure-imaginary]] [[hyperplane]].
