Contact discontinuities in multi-dimensional isentropic Euler equations. <i>Electronic Journal of Differential Equations, 2018</i>(94), pp. 1-11.1072-6691https://hdl.handle.net/10877/15261In this note we partially extend the recent nonuniqueness results on admissible weak solutions to the Riemann problem for the 2D compressible isentropic Euler equations. We prove non-uniqueness of admissible weak solutions that start from the Riemann initial data allowing a contact discontinuity to emerge.Text11 pages1 file (.pdf)enAttribution 4.0 InternationalIsentropic Euler equationsNon-uniquenessRiemann problemAdmissible weak solutionsContact discontinuityArticleThis work is licensed under a Creative Commons Attribution 4.0 International License.
