On Quasi-Norm Interpolation Error Estimation And A Posteriori Error Estimates for p-Laplacian

SIAM Journal on Numerical Analysis, 2002
The paper is devoted to the finite element approximation of the \(p\)-Laplacian with zero Dirichlet data. The authors establish a series of interpolation error estimates for several widely used averaging interpolators in some quasi-norms. These estimates are among the key ingredients in their improved a posteriori error analysis for the \(p\)-Laplacian.

Bounds and error estimates for radiosity

open access: yesProceedings of the 21st annual conference on Computer graphics and interactive techniques - SIGGRAPH '94, 1994
We present a method for determining a posteriori bounds and estimates for local and total errors in radiosity solutions. The ability to obtain bounds and estimates for the total error is crucial fro reliably judging the acceptability of a solution. Realistic estimates of the local error improve the efficiency of adaptive radiosity algorithms, such as ...
