WebIn this paper, we prove new results on Poincare and Friedrichs type gradient inequalities. In the case of Sobolev’s inequality, we get a new proof for the known R. Long and F. Nie’s result [13]. A unique approach has been applied for proving the mentioned inequalities based not on the representation formula or inequalities (see (1) below).
