The Fiedler Rose: On the extreme points of the Fiedler vector
Lawrence Christopher Evans
In this paper I present a counter-example to the conjecture: The Fiedler vector for the graph Laplacian of a tree has its most extreme values at the verticies which are the farthes…
Cosmological Constraints from Sunyaev-Zel'dovich-Selected Clusters with X-ray Observations in the First 178 Square Degrees of the South Pole Telescope Survey
B. A. Benson, T. de Haan, J. P. Dudley +73
We use measurements from the South Pole Telescope (SPT) Sunyaev Zel'dovich (SZ) cluster survey in combination with X-ray measurements to constrain cosmological parameters. We prese…
Optimal Constrained Investment in the Cramer-Lundberg model
Tatiana Belkina, Christian Hipp, Shangzhen Luo +1
We consider an insurance company whose surplus is represented by the classical Cramer-Lundberg process. The company can invest its surplus in a risk free asset and in a risky asset…
Minimal Cost of a Brownian Risk without Ruin
Shangzhen Luo, Michael Taksar
In this paper, we study a risk process modeled by a Brownian motion with drift (the diffusion approximation model). The insurance entity can purchase reinsurance to lower its risk…
On a coupled PDE model for image restoration
V. B. Surya Prasath, Dmitry Vorotnikov
In this paper, we consider a new coupled PDE model for image restoration. Both the image and the edge variables are incorporated by coupling them into two different PDEs. It is sho…
Luminous and High Stellar Mass Candidate Galaxies at z ~ 8 Discovered in CANDELS
Haojing Yan, Steven L. Finkelstein, Kuang-Han Huang +26
One key goal of the Hubble Space Telescope Cosmic Assembly Near-Infrared Deep Extragalactic Legacy Survey is to track galaxy evolution back to z ~ 8. Its two-tiered "wide and deep"…
