The stability of rational approximations of analytic semigroups
Artikel i vetenskaplig tidskrift, 1993
This paper contains two new characterizations of generators of analytic semigroups of linear operators in a Banach space. These characterizations do not require use of complex numbers. One is used to give a new proof that strongly elliptic second order partial differential operators generate analytic semigroups inL p , 1
