We present an approach for detecting and estimating the 3D poses of objects in images that requires only untextured CAD model no training phase new objects. Our combines Deep Learning geometry: It relies on embedding local geometry to match models input images. For points at surface objects, this can be computed directly from model; image locations, we learn predict it itself. This establishes ...

The purpose of this article is to revisit the relationship between ambiguous ideals and palindromy in the simple continued fraction expansions of quadratic irrationals begun by the first author and A. J. van der Poorten (1995, Bull. Austral. Math. Soc. 51, 215 233). We present simpler proofs of known results, new interrelationships, and correct some misinterpretations. We do this via the infras...

Standard economic models cannot capture the fact that information is often ambiguous, and is interpreted in multiple ways. Using a framework that distinguishes between the language in which statements are made and the interpretation of statements, we demonstrate that, unlike in the case where there is no ambiguity, players may come to have different beliefs starting from a common prior, even if...
