In topology, a branch of mathematics, the quasi-relative interior of a subset of a vector space is a refinement of the concept of the interior. Formally, if is a linear space then the quasi-relative interior of is where denotes the closure of the conic hull. Let is a normed vector space, if is a convex finite-dimensional set then such that is the relative interior. (Wikipedia).
You're there, and I'm here. And we're all on the Earth. But where is the Earth? In the Solar System, obviously, which is in the Milky Way, and so on. Think about your place in the cosmos, your exact spot in the Universe relative to everything else. It's time to get your bearings, and once

http://www.teachastronomy.com/ Most binary stars orbit slowly with a large distance between the two stars. However, a small fraction of binary systems are in close, tight, rapid orbits. In this situation mass transfer can occur from one star to the other. The system of two co-orbiting s

Emily Stark: The visual boundary of hyperbolic free-by-cyclic groups
Abstract: Given an automorphism of the free group, we consider the mapping torus defined with respect to the automorphism. If the automorphism is atoroidal, then the resulting free-by-cyclic group is hyperbolic by work of Brinkmann. In addition, if the automorphism is fully irreducible, th

http://www.teachastronomy.com/ For most planets in the solar system the orbital inclination is very small. That is, the axis defined by the north and south poles of the planet is almost exactly perpendicular to the plane of the planet's orbit of the Sun. The only two exceptions to this a
