SIAM Journal on Numerical Analysis, Vol. 57, No. 4 (2019), pp. 1897-1918 (22 pages) We study the spatial discretization of Westervelt's quasi-linear strongly damped wave equation by piecewise linear ...
We study in detail the log-linear return approximation introduced by Campbell and Shiller (1988a). First, we derive an upper bound for the mean approximation error, given stationarity of the log ...
