The simplest conditions to solve for a gravitational wave involve a metric disturbance under a gauge that is transverse and has a (*) zero value for this operation.
This operation, applied to the quantity "negative 1 to the fermion number times the negative exponential of beta H," generates a function which is equal to zero if supersymmetry is spontaneously broken, the Witten Index. This operation applied to the product of an entanglement witness and entangled state is always negative. The simplest conditions to solve for a gravitational wave involve a metric disturbance under a gauge that is transverse and has a (*) zero value for this operation. The expectation value of an operator in a state represented by a density matrix is equal to this operation on the density matrix times the operator. Contracting a rank-2 mixed tensor is equivalent to performing this operation, as exemplified by performing it on the Ricci tensor to obtain the Ricci scalar. For 10 points, name this operation which equals the sum of the diagonal elements of a matrix.
