introduction
\[u_t+6uu_x+u_{xxx}=0\]
- mKdV equation
$$ u_t+6u^2u_x+u_{xxx}=0 $$
- $N$-solution solution
$$ u(t,x)=-2\frac{\partial}{\partial x}\tan^{-1}[\frac{\Im \det (I+A)}{\Re \det (I+A)}] $$ where $I$ is the $N\times N$ matrix and $A$ denotes the $N\times N$ matrix with elements $$ A_{mn}=-\frac{d_n(t)}{\zeta_n+\zeta_m}\exp[i(\zeta_n+\zeta_m)x],\, m,n=1,2\cdots,N, $$ $\zeta_n=i\eta_n,\, \eta_n>0$ $d_n(t)=d_(0)\exp (8i\zeta_n^3 t)$
