Principle of analytic continuation
WebJan 1, 2024 · We present the Python package ana_cont for the analytic continuation of fermionic and bosonic many-body Green's functions by means of either the Padé approximants or the maximum entropy method. The determination of hyperparameters and the implementation are described in detail. The code is publicly available on GitHub, … Web(e)Let f(z) be an analytic function with u(x;y) = Re(f(x+ iy)) for (x;y) 2D. Show that f(x+ iy) has an analytic extension to a complex neighborhood of the origin, and that this f satis es the re ection principle f(x iy) = f(x+ iy) in a neighborhood of the origin. This shows that fhas an analytic continuation to some open part of the lower half ...

If f vanishes on an open subset of D, then f= 0 on D. Proof. The same proof as in one variable shows that the set E= fz2Djf(n)(z) = 0;8n2Nn g is closed as a countable intersection of closed sets E n= fz2Djf(n)(z) = 0 g. On the ...

Let us describe an application of the principle of analytic continuation to a problem in the theory of automorphic functions. Namely, we will show how to apply the principle in order to settle a conjecture of Peter Sarnak on triple products. As a corollary of our result we will get a new bound on Fourier coe–cients of ...

WebSep 5, 2024 · This was a little sloppy mathematically speaking and we will make it more precise here. 14.1: Analytic Continuation. If we have an function which is analytic on a region A, we can sometimes extend the function to be analytic on a bigger region. This is called analytic continuation. 14.2: Definition and properties of the Gamma function.
