A 'complex' is a whole that comprehends a number of parts, especially one with interconnected or mutually related parts. It may refer to:

★ Complex (chemistry), also called a "coordination compound" or "metal complex", is a structure consisting of a central atom or molecule weakly connected to surrounding atoms or molecules.

★ Complex (psychology), a group of mental factors that are unconsciously associated by the individual with a particular subject and influence the individual's attitude and behavior.

★ In geology, a complex is an assemblage of different rocks of any age origin that have been folded, intricately mixed, involved, or otherwise complicated, such that the rocks cannot be readily differentiated in mapping.

★ A complex number is a number of the form "''a'' + ''bi''", where ''a'' and ''b'' are real numbers and ''i'' is the imaginary number.

★ A complex system is a system comprised of interconnected simple parts that together exhibit a high degree of computational complexity from which emerges a higher order behavior.

★ A complex is an element of a complex algebra or field of sets.

★ A chain complex is a (possibly long) sequence of maps.

★ A simplicial complex is a kind of topological space that can be divided into fully adjacent triangles, or more generally, into simplices.

★ A CW complex, or closure-finite weak complex, is a kind of topological space, a generalization of the simplicial complex.
