The determination of solutions of similarity form is a mathematical subject of itself. One option for the task is to introduce the rescalings, \((\hat{x},\hat{\zeta })=(kx,\ell \zeta )\), and then to establish what combinations (if any) of the parameters k and \(\ell \) lead to the same equation as (69). One finds this to be so if \(k^2=\ell ^3\). The combination \(\chi =x/\zeta ^{3/2}=\hat{x}/\hat{\zeta }^{3/2}\) is therefore invariant under the transformation and implies the existence of a self-similar solution with \(U=U(\chi )\).

The first shock condition (Rankine-Hugoniot relation; see Whitham 1974) follows from first writing the mass-conservation equation in (98) as a integral conservation law,
$$\begin{aligned} 0 = \frac{{\mathrm d}}{{\mathrm d}t}\int _{x_1}^{x_2} \eta (x,t){\mathrm d}x + \left[ J(x,t)\right] _{x=x_1}^{x=x_2} = \int _{x_1}^{X} \eta _t(x,t) {\mathrm d}x \\ + \int _{X}^{x_2} \eta _t(x,t) {\mathrm d}x + \left[ J(x,t)-\dot{X}\eta (x,t)\right] _{x=x_1}^{x=x_2} , \end{aligned}$$where \(J=hu\) is the mass flux, \(x_1\) and \(x_2\) are arbitrary locations straddling the shock, and \(X^\pm \) implies the limit from either the left or right. By taking \(x_1\rightarrow X^-\) and \(x_2\rightarrow X^+\) and arguing that the remaining integrals then become negligible, we then find
$$ \dot{X} \left[ \eta (x,t)\right] _{x=X^-}^{x=X^+} = \left[ J(x,t)\right] _{x=X^-}^{x=X^+} . $$The second relation follows from applying the same argument to the momentum equation in (98) (\(\Gamma =0\)):
$$ \dot{X}{{\mathrm{Re}}}\left[ \eta u\right] _{x=X^-}^{x=X^+} = \left[ 2\eta \sigma - {1\over 2}{{\mathrm G}_{\mathrm z}}\eta ^2\right] _{x=X^-}^{x=X^+} . $$.

The restriction to varicose perturbations ignores the (very real) possibility that sinuous perturbations may be more unstable and dominate the break-up dynamics. Sinuous perturbations require a consideration of the bending of the midline of the fluid layer, along the lines considered in Sect. 4.5.

Note that there are typographical errors in the corresponding formulae for order-one curvature presented by Balmforth and Hewitt (2013). Specifically, the moment terms in their (95) and (116) should be \(-{\epsilon }\kappa M_s\), and that in (98) should be \(-\kappa M_s\).
