Abstract: | There are many papers in which approximate solution of Navier-Stokes problem is discussed by finite element method. Their error estimates are optimal, but degree of piecewise polynomials for pressure p or degree of piecewise polynomials for velocity u are not the lowest. In this papre a new element is given. Its degre for p and degree for u are the lowest and error estimates are optimal. |
