WebThis thesis concerns the development of a method for the detection of small solutions to delay diﬀerential equations. The detection of small solutions is im-portant because their presence has signiﬁcant inﬂuence on the analytical prop-erties of an equation. However, to date, analytical methods are of only limited practical use. WebNov 1, 2024 · With fractional delay differential equations new problems arise: the presence of the delay imposes to assign the solution not just at the initial point but on an entire interval. Due to the freedom in the choice of the initial function, some inconsistencies with the values forced by the fractional derivative are possible and the operators may ... toughman 2-in-1 insulated breathable wadersWebFeb 14, 2024 · Starting from the observation that artificial neural networks are uniquely suited to solving optimisation problems, and most physics problems can be cast as an optimisation task, we introduce a novel way of finding a numerical solution to wide classes of differential equations.
