After the Challenger: A Story of the Space Shuttle Disaster (Graphic Flash)

At school in Cocoa Beach, Florida, 15-year-old Dustin Martinez watches the Challenger space shuttle launch. He’s always been interested in the space program, but this launch is even more exciting. For the first time in history, a schoolteacher will be flying aboard the shuttle. Dustin’s father, however, isn’t interested. He wishes Dustin would spend more time on the family scallop boat than staring up at the stars. But when disaster strikes the shuttle, the two must join together, searching the seas and picking up the pieces of an American tragedy.

<p>Cluster algebras are combinatorially defined commutative algebras which were introduced by S. Fomin and A. Zelevinsky as a tool for studying the dual canonical basis of a quantized enveloping algebra and totally positive matrices. The aim of these notes is to give an introduction to cluster algebras which is accessible to graduate students or researchers interested in learning more about the field while giving a taste of the wide connections between cluster algebras and other areas of mathematics. The approach taken emphasizes combinatorial and geometric aspects of cluster algebras. Cluster algebras of finite type are classified by the Dynkin diagrams, so a short introduction to reflection groups is given in order to describe this and the corresponding generalized associahedra. A discussion of cluster algebra periodicity, which has a close relationship with discrete integrable systems, is included. This book ends with a description of the cluster algebras of finite mutation type and the cluster structure of the homogeneous coordinate ring of the Grassmannian, both of which have a beautiful description in terms of combinatorial geometry.
