We give some results about weighted minimal and weighted flat timelike general rotational surfaces in E 4 1 with density. Also, we construct some examples for these surfaces.eninfo:eu-repo/semantics/closedAccessTimelike General Rotational SurfaceDensityWeighted Mean CurvatureWeighted Gaussian CurvatureArticle10.4134/JKMS.j230260616105110712-s2.0-85208927226Q3WOS:001415847000001Q3
