 Radicals and Homomorphic Images of $C^*$-Algebras Commun. Korean Math. Soc. 1999 Vol. 14, No. 2, 365-371 Hyuk Han Seonam University Abstract : In this paper, we prove that the range of homomorphism from a C*-algebra $A$ into a commutative Banach algebra $B$ whose radical is nil contains no non-zero element of the radical of $B$. Using this result we show that there is no non-zero homomorphism from a C*-algebra into a commutative radical nil Banach algebra. Keywords : homomorphism, radical, quasi-nilpotent MSC numbers : 46H40, 46J45 Downloads: Full-text PDF
