Abstract : We obtain some necessary and sufficient conditions for the boundedness of the composition operators between weighted Bergman spaces of logarithmic weights. In terms of the conditions for the boundedness, we compute the essential norm of the composition operators.
Keywords : composition operator, logarithmic weighted, Bergman space, essential norm
