We consider the Seiberg-Witten solution of pure= 2 gauge theory in four dimensions, with gauge group SU (N). A simple exact series expansion for the dependence of the 2 (N− 1) Seiberg-Witten periods a I (u), a DI (u) on the N− 1 Coulomb-branch moduli u n is obtained around the ℤ 2N-symmetric point of the Coulomb branch, where all u n vanish. This generalizes earlier results for N= 2 in terms of hypergeometric functions, and for N= 3 in terms of Appell functions. Using these and other analytical results, combined with numerical computations, we explore the global structure of the Kähler potential K=Im (I a DI), which is single valued on the Coulomb branch. Evidence is presented that K is a convex function, with a unique minimum at the ℤ 2N-symmetric point. Finally, we explore candidate walls of marginal stability in the vicinity of this point, and their relation to the surface of vanishing Kähler potential.
