By assuming a Landesman-Lazer type condition and using a variational method based on the Minimum Principle, we show the existence of a weak solution in the Sobolev space W0 1,p (Ω).</dc:description><dc:publisher>Institute of Mathematics and Mechanics, National Academy of Sciences of Azerbaijan</dc:publisher><dc:date>2020</dc:date><dc:type>Article</dc:type><dc:identifier>https://rdlopen.rawdatalibrary.net/r/bayburt/13425</dc:identifier><dc:identifier>3005-8139</dc:identifier><dc:language>en</dc:language><dc:relation>Transactions of National Academy of Sciences of Azerbaijan.
