On Sobolev-Poincare-Friedrichs Type Weight Inequalities

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). http://lsec.cc.ac.cn/~zwy/papers/friedrichs.pdf WebWe present a direct proof of the discrete Poincar e{F riedrichs inequalities for a class of non-conforming approximations of the Sobolev space H1(), indicate optimal values of the … chubby boy meaning
