Asymptotic Characteristics of Compact Sets and Stepanets Classes

Ukrainian Mathematical Journal, 2001
Summary: We obtain estimates of the \(\varepsilon\)-entropy and \(\varepsilon\)-capacity of sets of periodic functions with a zero mean which possess a \((\psi,\beta)\)-derivative from the space \(L^2(0,2\pi)\).

On Donsker and Varadhan's asymptotic evaluation without compactness

Acta Mathematicae Applicatae Sinica, 1984
Consider a Feller semigroup of operators \(p_ t\) on C(X), the space of bounded continuous functions on a metric space X. The authors investigate the possibility of stating the Donsker and Varadhan limit relation \[ (A)\quad \lim_{t\uparrow \infty}t^{-1}\log p_ t1(x)=-\lambda_ 0 \] without assuming compactness of X.

Asymptotics: Compact Perturbations and Fredholm Theory

2002
Operator theory modulo compact perturbations should be regarded as a study of the “asymptotic” properties of operators. After making this vague notion more precise in the context of Hilbert space operators, we take up the general theory of compact and Fredholm operators acting on Banach spaces and discuss a remarkable asymptotic invariant, the Fredholm

Asymptotic number of maps on compact orientable surfaces

Discrete Mathematics and Applications, 2001
Summary: We get an asymptotic formula for the sum \[ Z_N= \sum_{b+p=N} F_{b,p}y^p, \quad\text{where} \quad F_{b,p}= \sum^\infty_{\rho=0} F_{b,p}(\rho), \] and \(F_{b,p} (\rho)\) is the number of maps of genus \(\rho\) with \(p+1\) vertices and \(p+b\) edges.

Asymptotic Expansions of Hermite Functions on Compact Lie Groups

Potential Analysis, 2002
Let \(G\) be a compact, connected Lie group of dimension \(n\). The author considers the compact group analogs of the classical Hermite polynomials on \(R^n\) generated by the heat kernel on \(G\). The asymptotic expansions (asymptotic series in powers of \(\sqrt t\)) of these Hermite functions are studied.

A compact and formal expression for asymptotic operators

Il Nuovo Cimento A, 1966
We derive a formal and compact form for asymptotic creation and annihilation operators. Connection to the well-known theory of formal scattering is given. The obtained formulas enable a study of commutation relations for elementary-particle asymptotic operators; some results pertinent in the cases where bound states are present are also given.
