$L$-analytic mappings in the disk algebra

Compact Endomorphisms of Certain Subalgebras of the Disk Algebra

Conformal Mappings in Geometric Algebra

I n 1878 William Kingdon Clifford wrote down the rules for his geometric algebra, also known as Clifford algebra. We argue in this paper that in doing so he laid down the groundwork that is profoundly altering the language used by the mathematical community to express geometrical ideas. In the real estate business everyone knows that what is most important is location. We demonstrate here that ...

Ideals of Denominators in the Disk-algebra

We show that there do not exist finitely generated, non-principal ideals of denominators in the disk-algebra A(D). Our proof involves a new factorization theorem for A(D) that is based on Treil’s determination of the Bass stable rank for H∞.
