A Hadamard-jensen inequality and an application to the elastic torsion problem
Sever S Dragomir, Grant Keady · Applicable Analysis · 2000
The (generalised) torsion function u of a domain Ω Rn is a function which is zero on the boundary of the domain and whose Laplacian is minus one at every point in the interior of the domain. Denote by │Ω│ the measure of Ω xc its centroid. We establish, for convex Ω Various improvements, generalisations and possible applications are discussed
