我们研究形式积分(Omega)f(D Omega)的积分,其中1R是连续的,omega是(k-1)-形式。我们引入了适当的凸性概念,即EXT。一个凸性,EXT。拟凸性和Ext.多凸性。我们研究了它们之间的关系,给出了几个例子和反例。最后,我们给出一个极小化问题的应用。
We study integrals of the form integral(Omega) f (d omega), where 1 R is continuous and omega is a (k - 1)-form. We introduce the appropriate notions of convexity, namely ext. one convexity, ext. quasiconvexity and ext. polyconvexity. We study their relations, give several examples and counterexamples. We conclude with an application to a minimization problem.
