Open Questions in Tiling

In the following survey, we consider connections between several open questions regarding tilings in general settings. Along the way, we support a careful revision of the de nition of aperiodicity, and pose several new conjectures. We also give several new examples. Over the years a number of interesting questions have been asked about the combinatorial complexity of tilings in the plane or oth...

Open Questions in Classical Gravity

We discuss some outstanding open questions regarding the validity and uniqueness of the standard second order Newton-Einstein classical gravitational theory. On the observational side we discuss the degree to which the realm of validity of Newton's Law of Gravity can actually be extended to distances much larger than the solar system distance scales on which the law was originally established. ...

Open questions in reverse mathematics

The objective of this paper is to provide a source of open questions in reverse mathematics and to point to areas where there could be interesting developments. The questions I discuss are mostly known and come from somewhere in the literature. My objective was to compile them in one place and discuss them in the context of related work. The list is definitely not comprehensive, and my choice o...
