  In chemistry, a complex, also called a "coordination compound" or "metal complex", is a structure consisting of a central atom or molecule connected to surrounding atoms or molecules....
  , also called a "coordination compound" or "metal complex", a structure consisting of a central atom or molecule weakly connected to surrounding atoms or molecules
• Protein complex
  Protein complex
  
  A multiprotein complex is a group of two or more proteins. Protein complexes are a form of quaternary structure. Proteins in a protein complex are linked by non-covalent protein-protein interactions, and different protein complexes have different degrees of stability over time....

  In psychology a complex is a group of mental factors that are unconsciously associated by the individual with a particular subject or connected by a recognizable theme and influence the individual's attitude and behavior....

• Complex (taxonomy), in biology, a cluster of species so closely related that they intergrade, can interbreed, and are difficult to firmly distinguish except at the extremes of their ranges
• A group of organisms involved in mimicry, being made of one or more mimics, models or dupes

  Imaginary number
  
  In mathematics, an imaginary number is a complex number whose square value is a real number not greater than zero. The imaginary unit, denoted by i or j, is an example of an imaginary number....

• Complex system
  Complex system
  
  A complex system is a system composed of interconnected parts that as a whole exhibit one or more properties not obvious from the properties of the individual parts....
  , a system of interconnected simple parts that together exhibit a high degree of computational complexity from which emerges a higher order behavior
• Complex analysis
  Complex analysis
  
  Complex analysis, traditionally known as the theory of functions of a complex variable, is the branch of mathematics investigating Function of complex numbers....
  , the study of functions of complex numbers.
• An element of a complex algebra or field of sets.
• Chain complex
  Chain complex
  
  In mathematics, a chain complex is a construct originally used in the field of algebraic topology. It is an algebraic means of representing the relationships between the cycle s and boundary in various dimensions of some "space"....
  , a (possibly long) sequence of maps
• Simplicial complex
  Simplicial complex
  
  In mathematics, a simplicial complex is a topological space of a particular kind, constructed by "gluing together" Point s, line segments, triangles, and their n-dimensional counterparts ....
  , a kind of topological space that can be divided into fully adjacent triangles, or more generally, into simplices
• CW complex
  CW complex
  
  In topology, a CW complex is a type of topological space introduced by J. H. C. Whitehead to meet the needs of homotopy theory. The idea was to have a class of spaces that was broader than simplicial complexes , but still retained a combinatorial nature, so that computational considerations were not ignored....
  , or closure-finite weak complex, a kind of topological space, a generalization of the simplicial complex
