Meromorphic function information

mathematical field of complex analysis, a meromorphic function on an open subset D of the complex plane is a function that is holomorphic on all of D except...

\Re (z)>0\,.} The gamma function then is defined as the analytic continuation of this integral function to a meromorphic function that is holomorphic in...

{\displaystyle \lim _{s\to 1}(s-1)\zeta (s)=1.} Thus the Riemann zeta function is a meromorphic function on the whole complex plane, which is holomorphic everywhere...

through the north pole (that is, the point at infinity). A meromorphic function is a complex function that is holomorphic and therefore analytic everywhere...

derivative exists in this more general region, making the zeta function a meromorphic function. The above equation no longer applies for these extended values...

In mathematics, the polygamma function of order m is a meromorphic function on the complex numbers C {\displaystyle \mathbb {C} } defined as the (m +...

Instead, modular functions are meromorphic: they are holomorphic on the complement of a set of isolated points, which are poles of the function. A modular form...

Rational functions are representative examples of meromorphic functions. Iteration of rational functions (maps) on the Riemann sphere creates discrete dynamical...

of complex analysis, Nevanlinna theory is part of the theory of meromorphic functions. It was devised in 1925, by Rolf Nevanlinna. Hermann Weyl called...

elliptic functions are special kinds of meromorphic functions, that satisfy two periodicity conditions. They are named elliptic functions because they...

a transcendental function is an analytic function that does not satisfy a polynomial equation, in contrast to an algebraic function. In other words, a...

Weierstrass function ℘ τ ( z ) {\displaystyle \wp _{\tau }(z)} belonging to the lattice Z + τ Z is a meromorphic function on T. This function and its derivative...

mathematics, an algebraic function is a function that can be defined as the root of an irreducible polynomial equation. Algebraic functions are often algebraic...
