A mass zero cluster expansion. Part 1: The Expansion
(Springer-Verlag, 1981-09)
A cluster expansion is developed and applied to study the perturbation λ(Δφ) 4 of the massless lattice field φ in dimension 3. The method is loosely inspired by the work of Gawedzki and Kupiainen on block spin techniques ...
Confidence intervals with fixed proportional accuracy
(Elsevier, 1986-1987)
The problem of setting a confidence interval with fixed proportional accuracy for the mean of a normal distribution is considered. A sequential procedure is proposed; and asymptotic expansions for its average coverage ...
Multi‐Duality in Minimal Surface—Type Problems
(Princeton University PressWiley Periodicals, Inc., 1995-08)
There may be simple P[aleph]1 and P[aleph]2-points and the Rudin-Keisler ordering may be downward directed
(Elsevier, 1987)
We prove the consistency, relative to ZFC, of each of the following two (mutually contradictory) statements. (A) Every two non-principal ultrafilters on m have a common image via a finite-to-one function. (B) Simple ...
On the diophantine equation apx + bqy = c + dpzqw
(Elsevier, 1990-06)
In this paper, the existence of effectively computable bounds on the solutions to the diophantine equation apx+bqy = c+dpzqw is shown. In this equation p, q are taken to be fixed relatively prime positive integers and a, ...
Singh's theorem in the lattice case
(Elsevier, 1988-12)
The asymptotic behavior of the parametric bootstrap estimator of the sampling distribution of a maximum likelihood estimator is investigated in a simple lattice case, integer valued random variables whose distributions ...
Construction of C 2 Pythagorean-hodograph interpolating splines by the homotopy method
(Baltzer Science Publishers, Baarn/Kluwer Academic Publishers; J.C. Baltzer AG, Science Publishers ; Springer Science+Business Media, 1996-12)
The complex representation of polynomial Pythagorean-hodograph (PH) curves allows the problem of constructing a C 2 PH quintic “spline” that interpolates a given sequence of points p 0 , p 1 ,..., p N and end-derivatives ...
Conservation laws and symmetries of generalized sine-Gordon equations
(Springer-Verlag, 1981-06)
We study some systems of non-linear PDE's (Eqs. 1.1 below) which can be regarded either as generalizations of the sine-Gordon equation or as two-dimensional versions of the Toda lattice equations. We show that these systems ...
Resonances, radiation damping and instabilitym in Hamiltonian nonlinear wave equations
(Springer-Verlag; Springer-Verlag Berlin Heidelberg, 1999-03)
We consider a class of nonlinear Klein-Gordon equations which are Hamiltonian and are perturbations of linear dispersive equations. The unperturbed dynamical system has a bound state, a spatially localized and time periodic ...
