几类超椭圆丢番图方程组的解

利用初等方法及超椭圆丢番图方程x4-Dy2=1的解与Pell方程基本解的关系,研究由两个超椭圆方程x4-D1y2=1和y4-D2z2=1构成的方程组,证明了该方程组至多只有一组正整数解;对于D1,D2的四类取值,给出了其唯一正整数解的求解公式.本文结果还说明,有无穷多个非平方的正整数D1,D2,使该方程组有正整数解.

Subjective intervention in formal models

Success in forecasting using mathematical/statistical models requires that the models be open to intervention by the user. In practice, a model is only one component of a forecasting system, which also includes the users/forecasters as integral components. Interaction between the user and the model is necessary to adequately cater for events and changes that go beyond the existing form of the model. In this paper we consider Bayesian forecasting models open to interventions, of essentially any form, to incorporate subjective information made available to the user. We discuss principles of intervention and derive theoretical results that provide the means to formally incorporate feedforward interventions into Bayesian models. Two example time series are considered to illustrate why and when such interventions may be necessary to sustain predictive performance.
