Jan 2, 2013 at 15:55	comment	added	Mahdi Majidi-Zolbanin		1) Your question needs an edit: you need $\sqrt{(x_1,\ldots,x_r)}=\sqrt{I}$, but for some reason this is not showing in your question properly. 2) You want which equality to hold? Do you want all three quantities (dimension, cohomological dimension and arithmetic rank) to be equal? Or do you want dimension and arithmetic rank to be equal? Or do you want dimension to be equal to cohomological dimension? etc.
