On the multisummability of WKB solutions of certain singularly perturbed linear ordinary differential equations [PDF]
Opuscula Mathematica, 2015 Using two concrete examples, we discuss the multisummability of WKB solutions of singularly perturbed linear ordinary differential equations. Integral representations of solutions and a criterion for the multisummability based on the Cauchy-Heine ...

Remarks on exact solutions [PDF]
General Relativity and Gravitation, 2006 This paper first discusses the historical context of the influential “Exact Solutions” book, which was co-authored by Malcolm MacCallum. It then makes various technical points about such solutions. It is useful to characterize solutions in terms of the properties of matter they contain or the kinds of test particle motions which are possible.

Exact solution of the Faddeev-Volkov model [PDF]
, 2007 The Faddeev-Volkov model is an Ising-type lattice model with positive Boltzmann weights where the spin variables take continuous values on the real line.

Exact solutions in bouncing cosmology
Physics Letters B, 2007 We discuss the effects of a (possibly) negative $(1+z)^6$ type contribution to the Friedmann equation. No definite answer can be given as to the presence and magnitude of a particular mechanism, because any test using the general relation $H(z)$ is able to estimate only the total of all sources of such a term. That is why we describe four possibilities:

Rashba coupling in quantum dots: exact solution [PDF]
, 2003 We present an analytic solution to the problem of the Rashba spin-orbit coupling in semiconductor quantum dots. We calculate the exact energy spectrum, wave-functions, and spin--flip relaxation times.

Exact solution of the nuclear pairing problem [PDF]
, 2000 In many applications to finite Fermi-systems, the pairing problem has to be treated exactly. We suggest a numerical method of exact solution based on SU(2) quasispin algebras and demonstrate its simplicity and practicality.

THE MATHEMATICAL MODEL OF DOME COVERING INDUSTRIAL FACILITY
Architecture and Engineering, 2017 A statically determinate flat truss models the industrial facility's arch. To derive dependence of structural deflection on the number of panels in a span, the Maxwell–Mohr equation, computer mathematics system Maple and the induction method are applied.
