Depth and restriction of multiplier ideals (Q659921)

Let \(a\) be an ideal sheaf on a smooth affine variety \(X\) of dimension \(\geq 2\), \(c\) a positive rational number, \(x\) a closed point of \(X\), and \({\mathcal J}(a^c)\) the multiplier ideal sheaf of \(a\) with weight \(c\). If depth\(_{x,X} {\mathcal O}/{\mathcal J}(a^c)\geq 2\) then a formula for the restriction of \({\mathcal J}(a^c)\) near \(x\) is given.
