Title: Navier-Stokes equation with slip-like boundary condition Authors: Kenichi Hashizume (Hiroshima Inst. of Technology, Japan) Tetsuya Koyama (Hiroshima Inst. of Technology, Japan) Mitsuharu Otani (Waseda Univ., Tokyo, Japan) Abstract: The aim of this note is to investigate a time-discretized 2-dimensional Navier-Stokes equation with a slip-like boundary condition, which arises in the melting ice problem. We prove the existence and uniqueness of a weak solution. Submitted August 22, 2008. Published May 04, 2009. Math Subject Classifications: 35Q30.
