This often means taking away or adding something, such that a third term slides in.
Korn's inequality proof
Did you know?
WebYoung's inequality is a special case of the weighted AM-GM inequality. It is very useful in real analysis, including as a tool to prove Hölder's inequality. It is also a special case of a more general inequality known as Young's inequality for increasing functions. Contents Statement of the Inequality Applications WebYoung's inequality states that if p,q p,q are positive reals satisfying \frac {1} {p}+\frac {1} {q}=1 p1 + q1 = 1, then ab \leq \frac {a^p} {p}+\frac {b^q} {q} ab ≤ pap + qbq for all nonnegative reals a,b a,b. It follows from the concavity of the logarithm function and Jensen's inequality; in particular,
Web1 mei 2008 · We investigate the character of the linear constraints which are needed for Poincaré and Korn type inequalities to hold. We especially analyze constraints which depend on restriction on subsets of positive measure and on the trace on a portion of the boundary. 2000 Mathematics Subject Classification: 26D15; 35R45, 74B05.
