View source for The symbolic computation of integrability structures for partial differential equations: Errata

Below is a list of known misprints in the book [[The symbolic computation of integrability structures for partial differential equations]].

# '''Page 57, the only displayed formula''' should be
#:::<math>  L=\left(\frac{1}{3}u(u_{xx}u_{tt} - u_{xt}^2) - \frac{1}{2}(u_xu_z + u_tu_y)\right)dx\wedge dz\wedge dt\wedge dy. </math>
#:(change the minus sign before <math>u_t u_y</math> into plus).
# '''Page 195, equation (10.9)''', replace it with
#:::<math>\sum_j \frac{\delta \Phi_{\mathcal{P}}}{\delta p^j}p^j = -2\Phi_{\mathcal{P}}</math>
#:(multiply the left-hand side by <math>p^j</math> to the right).
