We give conditions under which the demand function of a strictly convex preference relation can be constructed. ... In the appendix we introduce Brouwer's fan theorem (FT) and the notion of a weakly (uniformly) continuous predicate, and we give a version of the uniform continuity theorem for these predicates. ... If we are not interested in uniqueness of maxima, then we might suppose that ≻ only satisfies the weaker condition of being convex : for all x, y ∈ X and each t ∈ [0, 1], either (x + y)/2 x or (x + y)/ ...arXiv:1611.02542v1 fatcat:vvxu4ip5pvaivkwbwwbpwhrfqa
We apply the methods of thin position from knot theory to obtain a simple version of the three geodesics theorem for the 2-sphere . ... In general these three geodesics may be unstable, corresponding, for example, to the three equators of an ellipsoid. ... Figure 6 . wheel, fan, planar lollipop, and their dual graphs 17. Theorem.

For the class S of normalized univalent functions in the unit circle the best known such problem is of course the problem of Gronwall (1) to determine the maxima and the minima of |/(z)| and \f(z)\ for ... When f(x) is required to be increasing the solution of the extremal problem is thus uniquely determined apart from its value at the point x = c.

Let the class T have a unique mode at the point x = 0. The authors prove two limit theorems that show the relationships between Q and its two subclasses. ... There exist various bivariate and multivariate asymptotic (or sta- ble) distributions of extremes whose margins can be Gumbel, Fréchet or Weibull distributions of extremes (maxima or minima), mutually ...
By applying our earlier results together with the Fan-Glicksberg fixed-point theorem, we prove some ex- istence results for implicit variational inequalities and implicit quasi-variational inequalities ... For the coincidence-type equation («) Lx = Nx, where L, F: X — X x Y and X, Y are partially ordered Banach spaces, a theorem is obtained which states that, under some additional conditions, the existence ...
