| 2 | FINITE ELEMENT APPROXIMATION OF A NONLINEAR STEADY-STATE HEAT CONDUCTION PROBLEM显示文摘We examine a nonlinear partial differential equation of elliptic type with the homogeneous Dirichlet boundary conditions. We prove comparison and maximum principles. For associated finite element approximations we introduce a discrete analogue of the maximum principle for linear elements, which is based on nonobtuse tetrahedral partitions. | Michal Krizek (Mathematical Institute, Academy of Sciences, ■itn■ 25, CZ-115 67 Prague 1, Czech Republic) | 2001 | Journal of Computational Mathematics2001，19，1： | 0 |
| 3 | SPLITTING A CONCAVE DOMAIN TO CONVEX SUBDOMAINS显示文摘We examine a steady-state heat radiation problem and its finite element approximation in Rd, d = 2, 3. A nonlinear Stefan-Boltzmann boundary condition is considered. Another nonlinearity is due to the fact that the temperature is always greater or equal than 0[K]. We prove two convergence theorems for piecewise linear finite element solutions. | Li-ping Liu Michal Krizek(Mathematical Institute, Academy of Sciences, Zitna 25, CZ-11567 Prague 1, Czech Republic) | 1998 | Journal of Computational Mathematics1998，16，4： | 0 |
| 4 | OPTIMAL INTERIOR AND LOCAL ERROR ESTIMATES OF A RECOVERED GRADIENT OF LINEAR ELEMENTS ON NONUNIFORM TRIANGULATIONS显示文摘We examine a simple averaging formula for the gradieni of linear finite elemelitsin Rd whose interpolation order in the Lq-norm is O(h2) for d < 2q and nonuniformtriangulations. For elliptic problems in R2 we derive an interior superconvergencefor the averaged gradient over quasiuniform triangulations. Local error estimatesup to a regular part of the boundary and the effect of numerical integration arealso investigated. | I. Hlavacek M.
