Abstract Is it possible to maintain classical logic, stay close semantics, and yet accept that language might be semantically indeterminate? The article gives an affirmative answer by Ramsifying semantics , which yields a new semantic theory remains much closer than supervaluationism but at the same time avoids problematic presupposition of determinacy. resulting Ramsey is developed in detail, ...

This paper shows imperfect competition can lead to indeterminacy in aggregate output in a standard DSGE model with imperfect competition. Indeterminacy arises in the model from the composition of aggregate output. In sharp contrast to the indeterminacy literature pioneered by Benhabib and Farmer [3] and Gali [19], indeterminacy in our model is global; hence it is more robust to structural param...

In historical indeterminacy, it is known that an event stored in a temporal database did in fact occur, but it is not known exactly when the event occurred. We present the possible tuples data model, in which each indeterminate event is represented with a set of possible events that delimits when the event might have occurred, and a probability distribution over that set. We extend the TQuel qu...

This paper presents a consistent theory for describing indeterminacy and uncertainty of three-dimensional (3-D) reconstruction from a sequence of images. First, we give a group-theoretical analysis of gauges and gauge transformations. We then discuss how to evaluate the reliability of the solution that has indeterminacy and extend the CramerRao lower bound to incorporate internal indeterminacy....

This paper analyzes an incomplete ...nancial markets model with pricetaking utility-maximizing ...nancial innovators and no-short sales restrictions. It is shown that, given the indeterminacy of the no arbitrage price conjecture of innovators, ...nancial markets can remain incomplete in equilibrium. As a consequence, real indeterminacy of degree at least equal to int (S/2)(S(S/2)) results, wher...
