Unity High School competes in the West Central Conference and is a member school in the Illinois High School Association. The UHS mascot is the Mustang, with school colors of maroon, white, and Columbia blue. Due to their small enrollment, they combine for football with Payson-Seymour High School. [2] [4] [5]
That is, an element u of a ring R is a unit if there exists v in R such that = =, where 1 is the multiplicative identity; the element v is unique for this property and is called the multiplicative inverse of u. [1] [2] The set of units of R forms a group R × under multiplication, called the group of units or unit group of R.
X&Y is the third studio album by British band Coldplay, released on 6 June 2005 by Parlophone in the United Kingdom, and a day later by Capitol Records in the United States. Produced by Coldplay and producer Danton Supple , the album was recorded during a turbulent period for the band, during which their manager and creative director, Phil ...

In mathematics, the unitary group of degree n, denoted U(n), is the group of n × n unitary matrices, with the group operation of matrix multiplication.The unitary group is a subgroup of the general linear group GL(n, C), and it has as a subgroup the special unitary group, consisting of those unitary matrices with determinant 1.
The product and the multiplicative inverse of two roots of unity are also roots of unity. In fact, if x m = 1 and y n = 1, then (x −1) m = 1, and (xy) k = 1, where k is the least common multiple of m and n. Therefore, the roots of unity form an abelian group under multiplication. This group is the torsion subgroup of the circle group.
In mechanics, strain is defined as relative deformation, compared to a reference position configuration. Different equivalent choices may be made for the expression of a strain field depending on whether it is defined with respect to the initial or the final configuration of the body and on whether the metric tensor or its dual is considered.
An isotopy of an algebra is a triple of bijective linear maps a, b, c such that if xy = z then a(x)b(y) = c(z). For a = b = c this is the same as an automorphism. The isotopy group of an algebra is the group of all isotopies, which contains the group of automorphisms as a subgroup.
