Triple

Target class: gauge/gravity duality model
Context triple: [Klebanov–Strassler solution, instanceOf, gauge/gravity duality model]

• A. holographic duality chosen
  Holographic duality is a theoretical principle in physics stating that a gravitational theory in a higher-dimensional spacetime is exactly equivalent to a non-gravitational quantum field theory living on its lower-dimensional boundary.
• B. gauge theory
  A gauge theory is a type of field theory in which the laws of physics are invariant under continuous local transformations of certain internal symmetries, leading to the introduction of gauge fields that mediate fundamental interactions.
• C. electric–magnetic duality
  Electric–magnetic duality is a symmetry in certain physical theories that interchanges electric and magnetic fields or charges, often mapping a strongly coupled description of a system to a weakly coupled one while preserving its physical content.
• D. gravitational field model
  A gravitational field model is a conceptual representation that describes how mass generates a field influencing the motion and interaction of other masses through gravitational forces in space and time.
• E. non-singular black hole model
  A non-singular black hole model is a theoretical description of a black hole whose core avoids the classical spacetime singularity, typically by invoking modified gravity or quantum effects that yield a finite, regular interior geometry.
• F. None of above.
