Unitary divisor — In mathematics, a natural number a is a unitary divisor of a number b if a and frac{b}{a} are coprime, having no common factor other than 1. Thus, 5 is a unitary divisor of 60, because 5 and frac{60}{5}=12 have only 1 as a common factor, while 6… … Wikipedia
Unitary perfect number — A unitary perfect number is an integer which is the sum of its positive proper unitary divisors, not including the number itself. (A divisor d of a number n is a unitary divisor if d and n / d share no common factors.) Some perfect numbers are… … Wikipedia
Special unitary group — In mathematics, the special unitary group of degree n , denoted SU( n ), is the group of n times; n unitary matrices with determinant 1. The group operation is that of matrix multiplication. The special unitary group is a subgroup of the unitary… … Wikipedia
