Title: Global solutions with C^k-estimates for bar-d-equations on q-concave intersections Authors: Shaban Khidr (King Abdelaziz Univ., Jeddah, Saudi Arabia) Moulay-Youssef Barkatou (Univ. de Poitiers, Cedex, France) Abstract: We construct a global solution to the $\bar{\partial}$-equation with $\mathcal{C}^k$-estimates on q-concave intersections in $\mathbb{C}^n$. Our main tools are integral formulas. Submitted November 20, 2012. Published February 28, 2013. Math Subject Classifications: 32A26, 32F10, 32W05, 32W10.
