TY - JOUR T1 - Obstacle Problems for Scalar Ginzburg-Landau Equations JO - Journal of Partial Differential Equations VL - 1 SP - 49 EP - 56 PY - 2004 DA - 2004/02 SN - 17 DO - http://doi.org/ UR - https://global-sci.org/intro/article_detail/jpde/5375.html KW - Laplacian operator KW - obstacle problem KW - free boundary KW - positive solution AB - In this note, we establish some estimates of solutions of the scalar Ginzburg-Landau equation and other nonlinear Laplacian equation Δu = f(x, u). This will give an estimate of the Hausdorff dimension for the free boundary of the obstacle problem.
