Landau-Type Theorems for Certain Biharmonic Mappings
Let F(z)=|z|2g(z)+h(z) (|z|<1) be a biharmonic mapping of the unit disk 𝔻, where g and h are harmonic in 𝔻. In this paper, the Landau-type theorems for biharmonic mappings of the form L(F) are provided. Here L represents the linear complex operator L=(z∂/∂z)-(z¯∂/∂z)¯ defined on the class of com...
