  2. Vor einem Tag · Using Fourier analysis, we show how selection on a trait due to its environmental effects can be understood in terms of the way that a focal individual influences the fitness of all future individuals at all spatial positions via a modification to the environment these individuals encounter, whose importance depends on the relatedness between these and the focal. Simply put, natural selection ...

In mathematics, the Laplace transform, named after Pierre-Simon Laplace ( / ləˈplɑːs / ), is an integral transform that converts a function of a real variable (usually , in the time domain) to a function of a complex variable (in the complex-valued frequency domain, also known as s-domain, or s-plane ).

Vor 3 Tagen · n π x ℓ and cos nπx ℓ, cos. ⁡. n π x ℓ, where n = 0, 1, 2, …, n = 0, 1, 2, …, are solutions of the following Sturm--Liouville problem: y′′ + λy = 0, y(θ) = y(θ + 2ℓ). y ″ + λ y = 0, y ( θ) = y ( θ + 2 ℓ). A Fourier series is a way to represent a function as the sum of simple sine waves.
