In this paper, we present a new method which will, under certain conditions, increase the range of validity of … In formal terms, the perturbative series is a asymptotic series: a useful approximation for a few terms, but ultimately inexact. The breakthrough from chaos theory was an explanation of why this happened: the small divisors occur whenever perturbation theory is applied to a chaotic system. Visa mer In mathematics and applied mathematics, perturbation theory comprises methods for finding an approximate solution to a problem, by starting from the exact solution of a related, simpler problem. A critical feature of the … Visa mer The earliest use of what would now be called perturbation theory was to deal with the otherwise unsolvable mathematical problems of celestial mechanics: for example the orbit of the Moon, which moves noticeably differently from a simple Keplerian ellipse because … Visa mer Perturbation theory was first devised to solve otherwise intractable problems in the calculation of the motions of planets in the solar system. For instance, Newton's law of universal gravitation explained … Visa mer Perturbation theory develops an expression for the desired solution in terms of a formal power series known as a perturbation series in some "small" parameter, that quantifies the deviation from the exactly solvable problem. The leading term in this … Visa mer Keeping the above example in mind, one follows a general recipe to obtain the perturbation series. The perturbative expansion is created … Visa mer Perturbation theory has been used in a large number of different settings in physics and applied mathematics. Examples of the "collection of equations" $${\displaystyle D}$$ include algebraic equations, differential equations (e.g., the equations of motion and … Visa mer The standard exposition of perturbation theory is given in terms of the order to which the perturbation is carried out: first-order perturbation theory or second-order perturbation theory, and whether the perturbed states are degenerate, which requires Visa mer
