10月10日(木) 16:15 -- 17:30 幡谷 泰史 (山口大学理学部) ``Decaying solution to a free surface problem without capillary'' <研究発表要旨> We present existence result of decaying (in time) solution to a Navier-Stokes system with free surface. Since surface tension effect is not taken into account, regularities of free surface and product estimates should be taken care of.
