An interesting observation concerning one of the extremum problems is its equivalent formulation as an extremum problem pdf involving the oscillator semi-norm of the pay-off functional. The hypothesis has led to a unique solution of Monin–Obukhov similarity equations in terms of simple expressions linking shear stress (momentum flux) and heat flux to mean wind shear and temperature gradient.
