Construction and smoothing of triangular Coons patches with geodesic boundary curves
Given three regular space curves r1(t), r2(t) r3(t), t [ 0, 1 ] that define a curvilinear triangle, we consider the problem of constructing a C2 triangular surface patch R(u1, u2...

Lombardi Drawings of Graphs
We introduce the notion of Lombardi graph drawings, named after the abstract artist Mark Lombardi. In these drawings, edges are represented as circular arcs rather than as line seg...

Financial equilibria in the semimartingale setting: Complete markets and markets with withdrawal constraints
We prove existence of stochastic financial equilibria on filtered spaces more general than the ones generated by finite-dimensional Brownian motions. These equilibria span complete...

Robustness of k-gon Voronoi diagram construction
In this paper, we present a plane sweep algorithm for constructing the Voronoi diagram of a set of non-crossing line segments in 2D space using a distance metric induced by a regu...

A nonsmooth Newton's method for control-state constrained optimal control problems
We investigate optimal control problems subject to mixed control-state constraints. The necessary conditions are stated in terms of a local minimum principle. By use of the Fischer...
