Add a definition In order to ensure there are no further periodic points we introduce a secondperturbativeterm. From theCambridge English Corpus All other symmetric andperturbativestates will continue to be represented by (2.6) and (2.7) with no source term. From theCambridge English Corpus Nevertheless, both cases have the passage to aperturbativesituation as a common starting point. From theCambridge English Corpus There can be problems with aperturbativetreatment even for magnetic configurations that are only slightly asymmetric. From theCambridge English Corpus The results to be given are ofperturbativetype. From theCambridge English Corpus The broken lines denote (a) the standardperturbativesolution and (b) the approximate solution described by (2.18) and (2.19). From theCambridge English Corpus The analysis of previous solutions is complicated byperturbativesolutions that may include moving ions, but our analysis does not include moving ions. From theCambridge English Corpus Perhaps the answer is a non-trivial question of formalism: the '+' (the + sign) found inperturbativeexpansions certainly represents more than the simple addition of numbers. From theCambridge English Corpus In this case the solution can be found analytically and the expression for absorbed energy coincides with the one obtained using quantum mechanics with a first orderperturbativeapproximation. From theCambridge English Corpus More recently, quantum field theory, which is the theory of elementary particles, is mostlyperturbative, and certainly its most spectacular successes are down to perturbation theory. From theCambridge English Corpus Iterates of the -perturbativeoperators, restricted to suitable finite-dimensional subspaces of generalized functions, give rise to finite-dimensional matrices, whose traces approximate the flat traces of these iterates. From theCambridge English Corpus For smallperturbativeforces acting over short timescales, these interactions act in a way similar to that of permanent junction points and confer elastic properties on the biofilm. From theCambridge English Corpus Since the main quantity in the problem of plasma radiation is the dipolar autocorrelation function of the radiator, we derive it using the path integral technique in itsperturbativeform. From theCambridge English Corpus We should, however, bear in mind that no matter whetherperturbativeresults have been positive or negative, they have always been a great source of progress. From theCambridge English Corpus These examples are from corpora and from sources on the web.
