    Graduate From killing equation to Lie algebra

    Hi, I want to know how can we arrive at the generators of Lie algebra if we have killing equation ? on the other words, In this attached image I want to know how can I arrive at communication relation (16) by starting from killing vector (14) and its constraint...
