## B. Analytical understanding of condensation 

A semi-analytical method can also be applied in understanding the condensation although the Eqs. (3.4) and (3.5) are coupled and nonlinear. The method consists in finding approximate solutions near the horizon and in the asymptotic AdS space and then smoothly matching the solutions at an intermediate point [41]. In particular in Ref. [42] an analytical expression for the critical temperature was obtained and the phase transition phenomenon was demonstrated. And the result obtained in this way is in a good agreement with the numerical result. In this section we use this analytical approach to study the condensation of the scalar operator in the Hoˇra va-Lifshitz black hole, and then compare the result with that obtained by numerical method.
