How this entity was disambiguated
This entity first appeared as the object of triple T9637314 — resolving that mention is where its identity was fixed. The disambiguator weighed these candidate entities and picked the highlighted one (or “None”, minting a new entity). This is how homonymy is resolved: the same surface form can point to different entities.

A.
Einstein–Yang–Mills equations
The Einstein–Yang–Mills equations are the coupled field equations that describe how non-abelian gauge fields (such as those in Yang–Mills theory) interact with and curve spacetime within the framework of general relativity.
-
B.
Bondi–Metzner–Sachs symmetry
Bondi–Metzner–Sachs symmetry is an infinite-dimensional group of asymptotic spacetime symmetries in general relativity that characterizes the gravitational field at null infinity, especially in the context of gravitational radiation.

C.
Born–Infeld electrodynamics
Born–Infeld electrodynamics is a nonlinear modification of classical Maxwell theory proposed to remove the infinite self-energy of point charges by introducing an upper bound on the electromagnetic field strength.

D.
Polyakov action in string theory
The Polyakov action in string theory is a reformulation of the string’s dynamics that treats the worldsheet metric as an independent field, providing a convenient starting point for quantizing strings and analyzing their conformal symmetry.
