In this talk, I will discuss some issues and recent results related to the viscous boundary layer theory. In particular, I will present a global existence result on classical soluition to the 2-dimensional unsteady Prandtl's boundary system; some convergence results on viscous solutions when the viscosity becomes small. Both non-slip and Navier-...

For a zero-sum stochastic game which does not satisfy the Isaacs condition, we provide a value function representation for an Isaacs-type equation whose Hamiltonian lies in between the lower and upper Hamiltonians, as a convex combination of the two. For the general case (i.e. the convex combination is time and state dependent) our representatio...

In joint work with Carla Savage, we studied the inversion sequence representation of Eulerian polynomials and their generalizations. This led us to new recurrences for the generalized Eulerian polynomials and their refinements. These recurrences, combined with a relaxed notion of interlacing polynomials, called compatible polynomials, can be use...

This lecture will focus on the situation when gradients of the objective function are not available to an optimization algorithm. We summarize algorithms for local optimization of a deterministic function, with particular attention directed to model-based trust-region methods. We provide foundations for the theory underlying these algorithms and...

Four job performance and encouragement posters in a proof sheet. Each poster is represented multiple times. Posters read (left to right): "When in doubt . . Ask! Zero Defects. Its up to you" : "ZD its up to you" : "Careless Assembly . . There is no little mistake. Zero Defects. Its up to you" : and "Pride in Performance is a Habit. Zero Defects....

Six Burroughs ElectroData Division executives hold up the "Zero Defects. Its Up to You" banner in front of them. They are standing in front of a map of the globe and a smaller sign that reads: "Burroughs Around the World."
