C∗-algebras without idempotents
Get PDFAbstractThe simplest statement of the main results are these: Let π be a free group on 2 generators. Let Cπ be the complex ring and L1π the ring extension to L1 sums. Then L1π contains no idempotents. Furthermore, if α ϵ Cπ, β ϵ L1π are nonzero, then αβ ≠0. The first result is in the direction of proving that a certain simple C∗-algebra has no idempotents yielding a counter-example to the suggestion that simple C∗-algebras are generated by their projections

An inversion formula for finding technology distribution of production functions
Get PDFAbstractWe solve the problem of finding the technology distribution for profit functions (equivalently production functions) in a discrete setting. This is done by finding an inversion formula for the profit function, making use of a sequence of recursively defined polynomials whose behavior is studied
