文摘In this paper,we study real Banach * algebras systematically.We present the right form of Pták’s inequality[1,4]in the real case,and generalize the results of Vukman in[3]to the general case(algebras with or without an identity).Moreover,this paper is a real analogue of Pták’s work[1] in the complex case.
