The image of the path gamma in C under the function f is called the trace. This usage of the term "trace" is unrelated to the same term applied to matrices or tensors.

A point x_0 is said to be a periodic point of a function f of period n if f^n(x_0)=x_0, where f^0(x)=x and f^n(x) is defined recursively by f^n(x)=f(f^(n-1)(x)).

An integral which has neither limit infinite and from which the integrand does not approach infinity at any point in the range of integration.

The word saltus has two different meanings: either a jump or an oscillation of a function.

(Deltau)_i^2=(u_i-u^_)^2, where u^_ is the average of {u_i}.

An equation or formula involving transcendental functions.

A function of a single variable (e.g., f(x), g(z), theta(xi), etc.).

If n=1,2 (mod 4), and the squarefree part of n is divisible by a prime p=3 (mod 4), then no difference set of order n exists. Equivalently, if a projective plane of order n ...

Codimension is a term used in a number of algebraic and geometric contexts to indicate the difference between the dimension of certain objects and the dimension of a smaller ...

The Cramér conjecture is the unproven conjecture that lim sup_(n->infty)(p_(n+1)-p_n)/((lnp_n)^2)=1, where p_n is the nth prime.
