Hi Authors, thanks for your nice work! In your paper, I wasn't able to understand how you arrived at Eq. (7). for U_k and V_k. In particular, why is A=K,R_j ^k.K^-1 and B=-K.t_j^k. (Similarly for Eq. 9). It would be super helpful if you could explain it further or direct me towards some resources to understand the same. Thanks in advance!

Hi @lalithnag. I think it is from the following equation, but I did not proof it very carefully. I find some more details (eq.2) in this paper.
