Algebraic Convergence of Pulled Fronts
ERCIM News Issue 50 p. 43- 43
Propagating fronts which separate regions of different behaviour are quite common in Nature. A particular situation arises if the state ahead of the front is linearly unstable, like in the spreading of an epidemic. Recently researchers at CWI and Leiden University isolated the universal part in the expression for the speed of such fronts. Their results bear on several nonlinear phenomena including gas discharges.
