Unified Solution of the Expected Maximum of a Random Walk and the Discrete Flux to a Spherical Trap
Satya N. Majumdar, Alain Comtet, Robert M. Ziff
Two random-walk related problems which have been studied independently in the past, the expected maximum of a random walker in one dimension and the flux to a spherical trap of par…
Optimal Control of Underactuated Nonholonomic Mechanical Systems
Islam I. Hussein, Anthony M. Bloch
In this paper we use an affine connection formulation to study an optimal control problem for a class of nonholonomic, under-actuated mechanical systems. In particular, we aim at m…
Galois-stability for Tame Abstract Elementary Classes
Rami Grossberg, Monica VanDieren
We introduce tame abstract elementary classes as a generalization of all cases of abstract elementary classes that are known to permit development of stability-like theory. In this…
Kleinian groups with discrete length spectrum
Richard D. Canary, Christopher J. Leininger
We characterize finitely generated torsion-free Kleinian groups for which the real length spectrum (without multiplicities) is discrete.
Personal computer realizations for two classics of quantum chemistry
S. M. Blinder
Hylleraas in 1929 carried out a variational computation on the Schrodinger equation for the helium atom which gave, for the first time, a ground-state energy in essential agreement…
Multi-Wavelength Studies of the Optically Dark Gamma-Ray Burst 001025A
K. Pedersen, K. Hurley, J. Hjorth +18
We identify the fading X-ray afterglow of GRB 001025A from XMM-Newton observations obtained 1.9-2.3 days, 2 years, and 2.5 years after the burst. The non-detection of an optical co…
