Question

This is the first word in the name of a family of sets that can be constructed by recursively gluing together cells of increasing even dimension. It’s not “outer,” but an operation named for this word on a vector space V is equivalent to taking the direct sum of two copies of V, or the direct product of V with a set named for this word. Wirtinger derivatives are used in a subfield of mathematics described by this adjective. Multivalued functions on a set described by this adjective may exhibit branch cuts. A stereographic projection maps the Riemann sphere to a plane described by “extended” (10[1])and this adjective. A subfield of mathematics (-5[1])named for this adjective (-5[1])studies contour integration and holomorphic functions. (10[1])For (10[1])10 points, what adjective describes (10[1])numbers of the form “a plus ib”? ■END■ (10[1]0[1])

ANSWER: complex [accept complexification; accept complex analysis; accept extended complex plane or complex plane; accept complex numbers]
