Character Space and Gelfand type representation of locally C^{*}-algebra
In this article, we identify a suitable approach to define the character
space of a commutative unital locally $C^{\ast}$-algebra via the notion of the
inductive limit of topological spaces. Also, we discuss topological properties
of the character space. We establish the Gelfand type representation between a
commutative unital locally $C^{\ast}$-algebra and the space of all continuous
functions defined on its character space. Equivalently, we prove that every
commutative unital locally $C^{\ast}$-algebra is identified with the locally
$C^{\ast}$-algebra of continuous functions on its character space through the
coherent representation of projective limit of $C^{\ast}$-algebras. Finally, we
construct a unital locally $C^{\ast}$-algebra generated by a given locally
bounded normal operator and show that its character space is homeomorphic to
the local spectrum. Further, we define the functional calculus and prove
spectral mapping theorem in this framework.
