One characteristic of the one-dimensional Gaussian window is that its TF energy distribution is a bi-variate Gaussian function. Therefore its TF energy countours are elliptical, so shearing the TF distribution along the time axis provides no new degrees of freedom that cannot be obtained by combinations of shearing along the frequency axis together with dilation. ...

... It satisfies the set of WDVV (associativity) equations in canonical variables. The geometric/integrable content of corrections in 1/N is an important, still unresolved, problem. The only way to construct systematically these corrections is to solve the set of loop equations. We find the subleading correction (the torus approximation) and discuss its possible singularities of the answer in the set of new parameters S_i. ...
