... variant of the blow up technique is proposed, but it is centered on a certain point y 0 instead of on the points x n . In order to do that, the values of the solutions in different points of Ω are ... important to obtain a pri- ori estimates for positive solutions of associated problems in bounded domains via some procedure of blow up. In this work, we obtain...
