Asymptotic Control Theory

Journal of the Society for Industrial and Applied Mathematics Series A Control, 1964
Abstract : Some general problems are described concerning the asymptotic behavior of control processes as the time-interval becomes infinite. Some partial results in the general case, and a detailed analysis of a one- dimensional control process are presented.

Asymptotic Equivalence of Bayes Cross Validation and Widely Applicable Information Criterion in Singular Learning Theory

Journal of machine learning research, 2010
In regular statistical models, the leave-one-out cross-validation is asymptotically equivalent to the Akaike information criterion. However, since many learning machines are singular statistical models, the asymptotic behavior of the cross-validation ...

Asymptotic Reactor Theory

Nuclear Science and Engineering, 1961
It is shown that the results of -- asymptotic reactor theory may be derived simply from the condition that an infinite medium (rather than the correct finite medium) diffusion equation be used to describe the thermal neutron fiux in a reactor. In an asymptotic (bare, homogeneous, thermal) reactor, it is possible to describe the thermal flux through ...

Diffusion Theory via Asymptotics

Transport Theory and Statistical Physics, 1989
It is known that classic diffusion theory can lead to negative scalar fluxes if the external source of particles is anisotropic. The usual derivation of diffusion theory, via a truncated spherical harmonics expansion, gives no consistent way of dealing with this lack of positivity.

Asymptotically Free Theories

1984
In constructing a theory, information about the properties of the coupling constants between the fields is of primary importance. In a general case, the coupling constants depend on the momenta. To emphasize this circumstance, the notion of effective (or running) coupling constant, or of effective charge, has been introduced.

Asymptotic perturbation theory

1966
In the foregoing chapters we have been concerned almost exclusively with analytic or uniform perturbation theory, in which the continuity in norm of the resolvent in the parameter plays the fundamental role. We shall now go into a study in which the basic notion is the strong continuity of the resolvent.

Theories between theories: Asymptotic limiting intertheoretic relations

Synthese, 1995
This paper addresses a relatively common “scientific” (as opposed to philosophical) conception of intertheoretic reduction between physical theories. This is the sense of reduction in which one (typically newer and more refined) theory is said to reduce to another (typically older and “coarser”) theory in the limit as some small parameter tends to zero.

Standard Asymptotic Theory

2017
AbstractThis book relies on maximum likelihood (ML) estimation of parameters. Asymptotic theory assumes regularity conditions hold when the ML estimator is consistent. Typically an additional third derivative condition is assumed to ensure that the ML estimator is also asymptotically normally distributed.

Appendix. Asymptotic theory

1994
Abstract We have derived the standard errors for the estimated parameters in a random coefficient model from the inverse of the information matrix. This approach is justified in a variety of methods by reference to results from asymptotic theory.
