A Computational Investigation of Wehler K3 Surfaces

This article examines dynamical systems on a class of K3 surfaces in P×P with an infinite automorphism group. In particular, this article develops an algorithm to find Q-rational periodic points using information over Fp for various primes p. This algorithm is then optimized to examine the growth of the average number of cycles versus p and to determine the number of Fpm -rational points. The p...

Contentious Contracts ¤ Ulrich Hege

This paper o¤ers an explanation of rationally incomplete contracts where incompleteness refers to unforeseen contingencies. Agents enter a relationship with two-sided moral hazard in which a commitment to discard parts of the joint resources may be ex ante e¢cient. This happens through costly legal dispute which arises when contract terms are missing for the undesirable outcomes. We show that a...

FT3 values. FT3 values in the 2 patients with antibodies to T2, T3, or their conjugates were 12.3 and 32.6 pmol/L for the Vitros FT3II assay. With the Vitros FT3 assay, FT3 concentrations in 2-fold diluted control sera were 96% (1.1%) [mean (SD)] of those in the nondiluted sera, and in 2-fold diluted sera from 2 patients taking diclofenac, FT3 concentrations were 95.9% and 96.3% of those in the...
