$\mathcal{A}$ -拟凸性的位势

Potentials for $\mathcal{A}$-quasiconvexity

Bogdan Raita

摘要:

我们证明了每个常秩算子$\mathcal{A}$在频率空间中都有一个正合势$\mathbb{B}$.我们使用这个事实表明,$\mathcal{A}$ -quasiconvexity的概念,可以测试对compensable支持的字段。我们还证明了无$\mathcal{A}$的Young测度是由序列$\mathbb{B}u_j$通过重心模移位生成的.

英文摘要:

We show that each constant rank operator $\mathcal{A}$ admits an exact potential $\mathbb{B}$ in frequency space. We use this fact to show that the notion of $\mathcal{A}$-quasiconvexity can be tested against compactly supported fields. We also show that $\mathcal{A}$-free Young measures are generated by sequences $\mathbb{B}u_j$, modulo shifts by the barycentre.
