The axis in the complex plane corresponding to zero real part, R[z]=0.

Let K be a finite complex, let h:|K|->|K| be a continuous map. If Lambda(h)!=0, then h has a fixed point.

An algorithm which isolates roots in the complex plane by generalizing one-dimensional bracketing.

A simplicial complex K is said to be locally finite if each vertex of K belongs only to finitely many simplices of K.

The unit lower half-disk is the portion of the complex plane satisfying {|z|<=1,I[z]<0}.

The simplicial complex formed from a family of objects by taking sets that have nonempty intersections.

The collection of twistors in Minkowski space that forms a four-dimensional complex vector space.

The unit upper half-disk is the portion of the complex plane satisfying {|z|<=1,I[z]>0}.

Let y_n be a complex number for 1<=n<=N and let y_n=0 if n<1 or n>N. Then (Montgomery 2001).

The average power of a complex signal f(t) as a function of time t is defined as <f^2(t)>=lim_(T->infty)1/(2T)int_(-T)^T|f(t)|^2dt, where |z| is the complex modulus (Papoulis ...
