我们在空间 $GSBV^p$ 中提出了一个紧致性结果,它将 Ambrosio 的经典陈述扩展到没有变形先验界限的问题。作为一个应用,我们重新审视了 Cagnetti、Dal Maso、Scardia 和 Zeppieri 最近建立的自由间断泛函的 $\Gamma$ 收敛结果。我们研究边值问题的序列并显示最小值和极小值的收敛性。
We present a compactness result in the space $GSBV^p$ which extends the classical statement due to Ambrosio to problems without a priori bounds on the deformations. As an application, we revisit the $\Gamma$-convergence results for free discontinuity functionals established recently by Cagnetti, Dal Maso, Scardia, and Zeppieri. We investigate sequences of boundary value problems and show convergence of minimum values and minimizers.
