Discussion

Three of these four hold for a function analytic in a region. The exception is

  • A.its modulus may attain a maximum at an interior point
  • B.it has a convergent Taylor expansion about each interior point
  • C.its integral round every closed contour in the region vanishes
  • D.its real part satisfies Laplace's equation

Answer: A

The maximum modulus principle forbids an interior maximum unless the function is constant: the largest modulus is taken on the boundary. The Taylor expansion, the vanishing contour integral on a simply connected region, and the harmonicity of the real part are all genuine consequences of analyticity
