factor,

in arithmetic, any number that divides a given number evenly, i.e., without any remainder. The factors of 12 are 1, 2, 3, 4, 6, and 12. Similarly in algebra, any one of the algebraic expressions multiplied by another to form a product is a factor of that product, e.g., a+b and ab are factors of a2b 2, since (a+b)(ab)=a2b2. In general, if r is a rootroot,
in mathematics, number or quantity r for which an equation f(r)=0 holds true, where f is some function. If f is a polynomial, r is called a root of f; for example, r=3 and r

The "if" direction is easy: if a k-bounded partition [sigma] is also a (k + 1)- core, then strong covers on the interval [0, [sigma]] are precisely the regular covers in the Young lattice, the starred tableaux of shape [sigma] are standard Young tableaux of shape [sigma], and the major index of a starred tableau of shape [sigma] is the classical major index for standard Young tableaux; the fact that the weighted correction factor is 1 then follows from the classical weighted version of the hook-length formula (2.
