Tenth District Economic Developments

The Tenth District economy grew at a moderate pace during 1996. The district economy expanded vigorously in early 1996 but slowed as the year progressed. Tight labor markets in many parts of the region appeared to limit job growth, particularly in the large trade and services sectors. A slumping cattle industry also curbed overall growth in parts of the district. Nonetheless, construction conti...

Tenth Prairie Analysis Seminar

If we have a real vector field in the plane, the integral curves foliate the plane. Similarly, if we have a complex vector field in C then the complex integral curves foliate space by Riemann surfaces. An example of a question one might ask, is whether these Riemann surfaces are dense in space. In the case of vector fields in the plane, this is impossible, but if we do it on a torus instead, it...

Abortion (Amendment) Bill.

I feel that this lack of support is basically because there are so few wives who are an integral part of their husband's practice, and that our colleagues have not known the resentment building up over the years endured by doctors whose wives are employed while they wait patiently for recognition. My wife, a state-registered nurse, has been associated with this practice over 25 years, the last ...

The Hilbert’s-Tenth-Problem Operator

For a ring R, Hilbert’s Tenth Problem HTP (R) is the set of polynomial equations over R, in several variables, with solutions in R. We view HTP as an operator, mapping each set W of prime numbers to HTP (Z[W−1]), which is naturally viewed as a set of polynomials in Z[X1, X2, . . .]. For W = ∅, it is a famous result of Matiyasevich, Davis, Putnam, and Robinson that the jump ∅′ is Turing-equivale...
