Also, we know from linear algebra that the composition of two linear transformations is always a linear transformation and that the inverse of an invertible linear

It follows that every surjective linear isometry of CSL algebras is the sum of an isomorphism and an anti-isomorphism, followed by a unitary multiplication. 1. Introduction In [K], R. Kadison proved that every linear isometry of one C*-algebra onto another is given by a …

Notice that any isometry of Rn with a ﬁxed point is conjugate to an isometry ﬁxing the origin by a translation. Thus linear algebra gives us a complete description of isometries of Rn with a ﬁxed point. The three dimensional case is particularly easy then: there is one rota- • Isometric linear operator: f(x) = Ax, where A is an orthogonal matrix. • If f1 and f2 are two isometries, then the composition f2 f1 is also an isometry. Theorem Any isometry f : Rn → Rn can be represented as f(x) = Ax+x0, where x0 ∈ Rn and A is an orthogonal matrix. Here is a collection of exercises based on those in Tondeur, Chapter 4.

Isometries of R2 can be described using linear algebra [1, Chap. 6],1 and this generalizes to isometries of Rn [2, Sect. 6.5, 6.11].2 However, we can describe isometries of R2 without linear algebra, using complex numbers by viewing vectors x y as complex numbers x+ yi. x yi x+ yi= x y

1994-01-01 · We study the Banach space isometries of triangular subalgebras of C*-algebras that contain diagonals in the sense of Kumjian.Under a mild technical assumption, we prove that every isometry between two such algebras decomposes as a direct sum of a unitary multiple of an isometric algebra isomorphism and a unitary multiple of an isometric algebra anti-isomorphism.
