Repeat sales indices are commonly used to estimate the trend in house prices. Two assumptions are made when estimating these indices: 1) that the house characteristics are unchanged between observed sales and 2) that the underlying shadow prices for those attributes are constant or change...

In this paper, we first propose a two-level nonlinear conservative difference scheme for solving the generalized Rosenau-Kawahara equation. The second-order convergence in $L_\infty$-norm of the scheme is proved by an induction argument and discrete energy method. And the the prior estimate in...
