While an equality A=B states that two mathematical expressions are equal, an inequation A!=B states that two expressions are not equal.

A relation R on a set S is irreflexive provided that no element is related to itself; in other words, xRx for no x in S.

A polynomial in which the sum of subscripts is the same in each term.

The Jacobsthal numbers are the numbers obtained by the U_ns in the Lucas sequence with P=1 and Q=-2, corresponding to a=2 and b=-1. They and the Jacobsthal-Lucas numbers (the ...

The jerk j is defined as the time derivative of the vector acceleration a, j=(da)/(dt).

A mathematical procedure for finding the best-fitting curve to a given set of points by minimizing the sum of the squares of the offsets ("the residuals") of the points from ...

S_n=sum_(i)eta_imu(E_i), where mu(E_i) is the measure of the set E_i of points on the x-axis for which f(x) approx eta_i.

A function periodic with period 2pi such that p(theta+pi)=-p(theta) for all theta is said to be Möbius periodic.

Always increasing; never remaining constant or decreasing. Also called strictly increasing.

Topological lower bounds in terms of Betti numbers for the number of critical points form a smooth function on a smooth manifold.
