comment is this function invertible ??
but for big big 'x' the dominant term is $ f(x)=x $ and the inverse of this is just $ g(x) $ , besides any function which can be drawn can be inverted, just reflect each point trough the line $ y=x $ to get the Numerical inverse of the function

comment Zeros of $ \frac{1}{B(xi)^{1/2}}((iA)^{ix})(ix)^{ix}+ \frac{1}{B(-xi)^{1/2}}((-iA)^{-ix})(-ix)^{-ix}=H(x)$
yes 'x' is real i search for the real zeros only :)

revised Zeros of $ \frac{1}{B(xi)^{1/2}}((iA)^{ix})(ix)^{ix}+ \frac{1}{B(-xi)^{1/2}}((-iA)^{-ix})(-ix)^{-ix}=H(x)$

comment An inverse mellin transform
in this case , can we find a function so $$ \frac{\zeta (1-s)}{\zeta (s)}= \int_{0}^{\infty}dt f(t)t^{s-1} $$

comment Separation of variables linear PDE
assume the domain is a rectangle :D or similar.. i am interested in how to split the solutions $ f(x,y)$ into a differential equation for 'x' and another differential equation for 'y'
