Cohyponormality of Unbounded Product of Composition Operators in L2 Spaces
Let X,A,μ be a σ-finite measure space. The composition operators Cϕ:DCϕ⟶L2μ are defined by Cϕf=f∘ϕ,f∈DCϕ, where ϕ are nonsingular transformations and DCϕ=f∈L2μ: f∘ϕ∈L2μ. Suppose that ϕ1,ϕ2,⋯,ϕn are nonsingular transformations of X, where n∈ℕ and n≥2. It is natural to define the product operator of c...
