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 (-5[1])projection (10[1])maps (10[1])the Riemann sphere to a plane described by “extended” (-5[1])and this adjective. A subfield of mathematics named for this adjective studies contour integration (10[1])and holomorphic functions. For 10 points, (10[1])what adjective describes numbers of the form (10[1])“a plus ib”? (10[2])■END■ (10[2]0[2])

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