## Locally Supported Approximate Identities on the Unit Ball

• We present a constructive theory for locally supported approximate identities on the unit ball in $$\mathbb{R}^3$$. The uniform convergence of the convolutions of the derived kernels with an arbitrary continuous function $$f$$ to $$f$$, i.e. the defining property of an approximate identity, is proved. Moreover, an explicit representation for a class of such kernels is given. The original publication is available at www.springerlink.com
