How to use Gronwall

WebThe main result is a type of fractional Grönwall inequality and we illustrate its use by outlining some stability and convergence estimates of schemes for fractional reaction-subdiffusion problems. This approach extends earlier work that used the familiar L1 approximation to the Caputo fractional derivative, and will facilitate the analysis of ... WebApr 9, 2016 · 1. There doesn't seem to be any need for the full force of Grönwall's inequality here. The much simpler differential form will suffice. But we'll need one trick: Let u ( t) = ψ ( t) − φ ( t). We need to show that u ≤ 0. So assume instead that u ( t 1) > 0, for some t 1 > t 0. Now define. WebThe first use of the Gronwall inequality to establish boundedness and stability is due to R.
