Joint Spectra of Generators in Topological Algebras

Let 𝒜 be a complex topological algebra with unit 1 and 𝒰 a family of proper closed ideals in 𝒜. For an arbitrary S⊂𝒜 we define a globally defined joint spectrum σ𝒰(S)={(λs)s∈S∈ℂS  |   ∃ I  ∈𝒰(s−λs)∈I ∀s∈S}. We prove that for S generating 𝒜 the spectrum σ𝒰(S) can be identified with the set 𝔐𝒰 of co...
