# The adjoint differential of the logarithmic map base point

This function evaluates for $F(x)=\log_xy$ with fixed $y\in\M$ the adjoint differenital $D^*_xF(x)[\eta].$

It is calculated a corresponding adjoint Jacobi field AdjJacoiField. Since the weights are the same as for the differential DxLog, we refer to that page for details.
