Regularization describes the transformed problem for DRQS in terms of parameter $p$, but at the same time it is using the letter 'p' for the regularization power and this is confusion, a quick fix would be to change $p$ to $q$ and leave the regularization term 'p'. This change should also be done for the transformed problem of DTRS
