Algebraic Extensions of Normed Algebras
Abstract
Description
We compare two known methods of extending a complex, unital, commutative normed algebra so as to include solutions to sets of monic polynomials over the original algebra. (One of these is a generalisation of a construction from the thesis of B. J. Cole and only applies to uniform algebras.) An example is given to show that they can lead to essentially different algebras.
Integrally closed extensions which generalise Cole's `universal root algebras' are also constructed .
