    • Pseudospectra of elements of reduced Banach algebras (Pre-published version) 

      Kulkarni, S H; Krishnan, Arundhathi (Springer, 2017)
      Let A be a Banach algebra with identity 1 and p ∈ A be a non-trivial idempotent. Then q = 1−p is also an idempotent. The subalgebras pAp and qAq are Banach algebras, called reduced Banach algebras, with identities p and q ...
