Abstract:For an open set urn:x-wiley:dummy:mana201300269:equation:mana201300269-math-0001 we study the algebra urn:x-wiley:dummy:mana201300269:equation:mana201300269-math-0002 of continuous linear operators on urn:x-wiley:dummy:mana201300269:equation:mana201300269-math-0003 admitting the monomials as eigenvectors. We give a concrete representation of these operators and evaluate it explicitly for the unit ball and the whole of urn:x-wiley:dummy:mana201300269:equation:mana201300269-math-0004. We also study the topology of urn:x-wiley:dummy:mana201300269:equation:mana201300269-math-0005 and the algebra of eigenvalue sequences.
Keywords:Operators on smooth functions  algebra of operators  monomials as eigenvectors  Primary: 47L80  47B38  Secondary: 46H35  46E10
