Link group

The link group of the Hopf link, the simplest non-trivial link – two circles, linked once – is the free abelian group on two generators, \mathbf{Z}^2. Note that the link group of two unlinked circles is the free nonabelian group on two generators, of which the free abelian group on two generators is a quotient.

Magdalen papyrus

The "Magdalen" papyrus was purchased in Luxor, Egypt in 1901 by Reverend Charles Bousfield Huleatt (1863–1908), who identified the Greek fragments as portions of the Gospel of Matthew (Chapter 26:23 and 31) and presented them to Magdalen College, Oxford, where they are cataloged as P. Magdalen Greek 17 (Gregory-Aland \mathfrak{P}64) and whence they have their name.

which, after multiplication by e {I \beta} just tells us that the Einstein tensor R {\alpha \beta} - {1 \over 2} R g {\alpha \beta} of the metric defined by the tetrads vanishes.

TrueSkill

Factor graphs are used to "pack up" each team into (\mu,\sigma) pairs on which the update formulas are run; the skill updates are then correctly distributed to each player.

he studied a weighted version of the set cover problem, and proved that a greedy algorithm provides good approximations to the optimal solution, generalizing previous unweighted results by David S. Johnson (J. Comp. Sys. Sci. 1974) and László Lovász (Discrete Math. 1975).

X-ray standing waves

The characteristic shape of Y p can be used to derive precise structural information about the surface atoms because the two parameters f H (coherent fraction) and P H (coherent position) are directly related to the Fourier representation of the atomic distribution function.
