WebMar 6, 2024 · In mathematics, Fisher's equation (named after statistician and biologist Ronald Fisher) also known as the Kolmogorov–Petrovsky–Piskunov equation (named after Andrey Kolmogorov, Ivan Petrovsky, and Nikolai Piskunov ), KPP equation or Fisher–KPP equation is the partial differential equation: ∂ u ∂ t − D ∂ 2 u ∂ x 2 = r u ( 1 − u). Webbeen found for the d-dimensional Fisher’s equation in [11]. Singular perturbation method has been applied to solve eq. (2) by Puri et al in [12,13]. Carey and Shen [7] solved the Fisher’s reaction–diffusion equation by a least-squares finite element approximation. In [14], a nonlinear transformation was introduced to solve the Fisher’s ...

However, when inflation occurs, a dollar repaid in the future is worth less than a dollar borrowed today. To calculate the true economics of the loan, it is necessary to adjust the nominal cash flows to account for future inflation. The Fisher equation can be used in the analysis of bonds.
