WebCorollary 3.5 (Principle of analytic continuation) Assume fis holomorphic in an open connected subset (=domain) of Cn. 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 ... WebDec 26, 2024 · Idea. Where ordinary 3d Chern-Simons theory is given by an action functional with values in the circle group ℝ / ℤ \mathbb{R}/\mathbb{Z} on a space of special unitary group-principal connections, its “analytic continuation”(Gukov 03, Witten 10) instead is defined on complex special linear group-principal connections and its values are …

Suppose f is an analytic function defined on a non-empty open subset U of the complex plane $${\displaystyle \mathbb {C} }$$. If V is a larger open subset of $${\displaystyle \mathbb {C} }$$, containing U, and F is an analytic function defined on V such that $${\displaystyle F(z)=f(z)\qquad \forall z\in U,}$$ … See more In complex analysis, a branch of mathematics, analytic continuation is a technique to extend the domain of definition of a given analytic function. Analytic continuation often succeeds in defining further … See more Begin with a particular analytic function $${\displaystyle f}$$.

Suppose $${\displaystyle D\subset \mathbb {C} }$$ is … See more A common way to define functions in complex analysis proceeds by first specifying the function on a small domain only, and then extending it by analytic continuation. In practice, this continuation is often done by first establishing … See more The power series defined below is generalized by the idea of a germ.
