Hessian in the spinfoam models with cosmological constant
Wojciech Kamiński, Qiaoyin Pan
In this paper, we introduce a general method to prove the non-degeneracy of the Hessian in the spinfoam vertex amplitude for quantum gravity and apply it to the spinfoam models wit…
Spiraling conformal geodesics
Wojciech Kamiński
In this short note, we construct an example of spiraling conformal geodesic in Euclidean signature in dimension , answering the question posed by Helmuth Friedrich and Paul Tod,…
Extreme horizon equation
Wojciech Kamiński, Jerzy Lewandowski
Extremal horizons satisfy an equation induced by the Einstein vacuum equations that determines the shape of the horizon and the manner in which it rotates (the EEH equation). Until…
Symplectic charges in the Yang-Mills theory of the normal conformal Cartan connection: applications to gravity
Adam Bac, Wojciech Kamiński, Jerzy Lewandowski +1
It is known that a source-free Yang-Mills theory with the normal conformal Cartan connection used as the gauge potential gives rise to equations of motion equivalent to the vanishi…
