Decarbonization of Cities in AsiaThen we solve the Euler equations and exact equations. The method of undetermined coefficients for solving inhomogeneous linear ordinary differential equations is also presented. Furthermore, we give the method of variation of parameters for solving second-order inhomogeneous linear ordinary differe

Decarbonization of Maritime Transportrespectively. The two-soliton solution is also determined via the Hirota bilinear presentation. The KP equation is an extension of the KdV equation. We use symmetry transformations to extend the solutions of the KdV equation to the more sophisticated solutions of the KP equation. Then we solve the K

Decarbonize Public and Commercial Buildings,tric ideas and moving frames to solve two-dimensional Boussinesq equations with partial viscosity terms and three-dimensional stratified rotating Boussinesq equations. We obtain new families of explicit exact solutions with multiple parameter functions; many of them are periodic, quasi-periodic, and
