The solution is shown to be unique. Because of selfsimilarity the problem is reduced to solve a system of algebraic equations of degree two. The solution is constructed by a method of continuity and obtained by solving associated ordinary differential equations. The selfsimilar expanding solution is useful to construct a crystalline flow from an arbitrary polygon not necessarily admissible.Department of Mathematics, Hokkaido UniversityDepartmental Bulletin Paperapplication/pdfhttp://hdl.handle.net/2115/69456info:doi/10.14943/83802https://eprints.lib.hokudai.ac.jp/dspace/bitstream/2115/69456/1/pre649.pdfHokkaido University Preprint Series in Mathematics6491192004engpublisher
