For a real number α [alpha] the Dirichlet-type spaces 𝔇α [script D sub alpha] are the family of Hilbert spaces consisting of all analytic functions f(z) = ∑n=0∞[sum over n equals zero to infinity] ˆf(n) [f hat of n] zn [z to the n] defined on the open unit disc 𝔻 [unit disc] such that
∑n=0∞ (n+1)α | ˆf(n) |2
[sum over n equals 0 to infinity] [(n+1) to α] [ | f hat of n | to 2]
is finite.
For α < 0, the spaces 𝔇α are known as weighted Bergman spaces. When …
