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). razormind payday 2 roblox song id

WebIn mathematics, Friedrichs's inequality is a theorem of functional analysis, due to Kurt Friedrichs.It places a bound on the L p norm of a function using L p bounds on the weak derivatives of the function and the geometry of the domain, and can be used to show that certain norms on Sobolev spaces are equivalent.
