From the Preface: K-theory was once brought by way of A. Grothendieck in his formula of the Riemann- Roch theorem. for every projective algebraic style, Grothendieck developed a gaggle from the class of coherent algebraic sheaves, and confirmed that it had many great homes. Atiyah and Hirzebruch considered a topological analog outlined for any compact house X, a gaggle K{X) made from the class of vector bundles on X.

Viewing H as an affine algebraic variety the algebra C[P] is just the ring of regular functions on H, or equivalently the ring of holomorphic functions on H with moderate growth at infinity.
