Bergman space


Let Gn be a domain and let dV denote the Euclidean volume measure on G.

Definition.

Let

A2(G):={f holomorpic in G|G|f(z)|2𝑑V(z)<}.

A2(G) is called the Bergman space on G. The norm on this space is defined as

f:=G|f(z)|2𝑑V(z).

Further we define an inner product on A2(G) as

f,g:=Gf(z)g(z)¯𝑑V(z).

The inner product as defined above really is an inner product and further it can be shown that A2(G) is completePlanetmathPlanetmathPlanetmath since convergence in the above norm implies normal convergence (uniform convergenceMathworldPlanetmath on compact subsets). The space A2(G) is therefore a Hilbert spaceMathworldPlanetmath. Sometimes this space is also denoted by La2(G).
