关于无界多重积分的松弛问题

On the relaxation of unbounded multiple integrals

Omar Anza Hafsa, Jean Philippe Mandallena

摘要:

研究变分法中的多重积分的松弛问题,其中被积函数是非凸的,有效域是凸的,并且可以取值\infty .我们使用局部技术的基础上的措施参数,证明了整表示在索伯列夫空间的功能是几乎处处可微。在标量的情况下,并在拟凸增长和p(x)-增长的被积函数的情况下的应用。

英文摘要:

We study the relaxation of multiple integrals of the calculus of variations, where the integrands are nonconvex with convex effective domain and can take the value \infty. We use local techniques based on measure arguments to prove integral representation in Sobolev spaces of functions which are almost everywhere differentiable. Applications are given in the scalar case and in the case of integrands with quasiconvex growth and p(x)-growth.
