Such a system is governed by the biharmonic nonlinear Schrodinger equation Figure 3: Simulations of the propagation of a fundamental and a higher-order pure-quartic soliton along five quartic ...

Given any cubic or quartic equation with real coefficients, it can be transformed by a change of variable into a standard form, and thus solved by means of a double-sided scale (Fig. 1 ...

Kronecker subsequently obtained the same solution more simply, and Brioschi also derived the equation. To do so, reduce the general quintic A quintic also can be algebraically reduced to principal ...

Although these restrictions sound severe, the Bernoulli equation is very useful, partly because it is very simple to use and partly because it can give great insight into the balance between pressure, ...
