In a convenient space of distributions, we will see the emergence of a delta standing wave which extends the corresponding result, obtained by Sun in 2013 and also by Shen in 2014, for a linear flux. In the nonlinear setting, a new phenomenon arises: starting from a vanishing initial condition, the concentration of matter in a fixed point becomes possible. These results are easy to get essentially because, in our approach, the product of distributions is a distribution that does not depend of approximation processes.<\/jats:p>","DOI":"10.1063\/1.5086161","type":"journal-article","created":{"date-parts":[[2019,7,12]],"date-time":"2019-07-12T11:44:16Z","timestamp":1562931856000},"update-policy":"https:\/\/doi.org\/10.1063\/aip-crossmark-policy-page","source":"Crossref","is-referenced-by-count":1,"title":["A nonlinear conservation law with a step function involving the flux: A distributional approach"],"prefix":"10.1063","volume":"60","author":[{"given":"C.
