Denote the free group on 2 letters by F2 and the SL(2,C)-representation variety of F2 by R = Hom(F2, SL(2,C)). The group SL(2,C) acts on R by conjugation. We construct an isomorphism between the coordinate ring C[SL(2,C)] and the ring of matrix coefficients, providing an additive basis of C[R]SL(2,C) in terms of spin networks. Using a graphical calculus, we determine the symmetries and multipli...

Escalation in the number of different modes of life includes the exploitation of a greater range of levels above and below the sediment surface (tiering), as well as diversification of feeding mechanisms and modes of locomoti...
متن کاملJournal of Statistics Education, v17n2: Leigh Lawton
Hypothesis testing is one of the more difficult concepts for students to master in a basic, undergraduate statistics course. Students often are puzzled as to why statisticians simply don’t calculate the probability that a hypothesis is true. This article presents an exercise that forces students to lay out on their own a procedure for testing a hypothesis. The result is that the students develo...

The common congenital lung malformations have traditionally been divided into separate pathological entities such as pulmonary airway malformations, cystic adenomatoid malformations, congenital lobar emphysema, intra or extra pulmonary sequestrations, bronchogenic and foregut cysts. Some may produce respiratory compromise immediately after birth or even in utero. The management of such life thr...
