流形值BV-空间中变分问题的均匀化

Homogenization of variational problems in manifold valued BV-spaces

Jean-Francois Babadjian, Vincent Millot

摘要:

本文推广了\cite{BM}关于Sobolev映射的线性增长积分泛函的均匀化的结果。通过$Γ$ -收敛分析,我们确定了均匀化的能量在有界变差函数的空间。结果表明,对于值在流形上的$BV$ -映射,它是有限的。能量的体积和康托部分涉及\cite{BM}中引入的切向均匀化密度,而跳跃部分涉及流形上的测地线型问题给出的均匀化表面密度。

英文摘要:

This paper extends the result of \cite{BM} on the homogenization of integral functionals with linear growth defined for Sobolev maps taking values in a given manifold. Through a $Γ$-convergence analysis, we identify the homogenized energy in the space of functions of bounded variation. It turns out to be finite for $BV$-maps with values in the manifold. The bulk and Cantor parts of the energy involve the tangential homogenized density introduced in \cite{BM}, while the jump part involves an homogenized surface density given by a geodesic type problem on the manifold.
