Everywhere ramified towers of global function fields
Iwan Duursma, Bjorn Poonen, Michael Zieve
We consider a tower of function fields F_0 < F_1 < ... over a finite field such that every place of every F_i ramified in the tower and the sequence genus(F_i)/[F_i:F_0] has a fini…
Dimension reduction based on constrained canonical correlation and variable filtering
Jianhui Zhou, Xuming He
The ``curse of dimensionality'' has remained a challenge for high-dimensional data analysis in statistics. The sliced inverse regression (SIR) and canonical correlation (CANCOR) me…
Online Scheduling to Minimize the Maximum Delay Factor
Chandra Chekuri, Benjamin Moseley
In this paper two scheduling models are addressed. First is the standard model (unicast) where requests (or jobs) are independent. The other is the broadcast model where broadcasti…
Analytic continuation from a family of lines
Alexander Tumanov
Given a function f in the exterior of a convex curve in the real plane, we prove that if the restrictions of f to the tangent lines to the curve extend as entire functions, then th…
Convexity and smoothness of scale functions and de Finetti's control problem
A. E. Kyprianou, V. Rivero, R. Song
Under appropriate conditions, we obtain smoothness and convexity properties of -scale functions for spectrally negative Lévy processes. Our method appeals directly to very recen…
