Streszczenie
An operator $M$ acting on the space of real analytic functions $\mathscr {A}(\mathbb {R})$ is called a multiplier if every monomial is its eigenvector. In this paper we state some results concerning strongly continuous semigroups generated by Hadamard multipliers. In particular we show when an Euler differential operator of finite order is a generator and when it is not.
