- W2891277544 abstract "Let (mathcal {H}) be a Hilbert space. The Banach space (mathsf {B}(mathcal {H})) of bounded operators on (mathcal {H}) is an algebra over (mathbb {C}) with multiplication defined as composition of operators and the identity operator Open image in new window is the unit (neutral element of multiplication) of this algebra. The operation of passing to the adjoint operator $$displaystylemathsf {B}(mathcal {H})ni {x}longmapsto {x^*}in mathsf {B}(mathcal {H})$$is an anti-linear, anti-multiplicative involution (for any (xin mathsf {B}(mathcal {H})) we have x∗∗ = x). Moreover, the operator norm is compatible with algebra structure in the sense that $$displaystyle|xy|leq |x||y|,qquadquad{x,y}in mathsf {B}(mathcal {H}).$$In particular (mathsf {B}(mathcal {H})) is a Banach algebra ." @default.
