Let,s suppose we have a classical equation:(adsbygoogle = window.adsbygoogle || []).push({});

[tex]F(x,y,dy/dx,.....)=0[/tex]

but this can not be derived from a Lagrangian or a Hamiltonian..then how would we quantizy it?..

Another question given the Lagrangian with position and velocities...could we obtain a quantization of it,i mean obtain a quantummechanics based on position and velocities instead of in momenta and positions..
