Michael Ruzhansky, Serikbol Shaimardan, Kanat Tulenov

AI总结:

该研究在非交换欧几里得空间框架下推导Sobolev不等式及相关推论,证明对数Sobolev不等式与Nash不等式等价,并将结果应用于非线性偏微分方程适定性与热方程解的时间衰减分析。

摘要:

本文研究了非交换欧几里得空间上的Sobolev不等式。作为一个简单推论,我们得到了Gagliardo-Nirenberg型不等式,并且作为其应用,我们证明了非交换欧几里得空间中非线性偏微分方程的全局适定性。此外,我们通过补全文献[37]中非交换Varopoulos定理的条目,证明了在该非交换框架下,对数Sobolev不等式与Nash不等式等价(二者常数可能不同)。最后,我们给出了Nash不等式的一个直接应用,用于计算非交换情形下热方程解的时间衰减性。

英文摘要:

In this work, we study the Sobolev inequality on noncommutative Euclidean spaces. As a simple consequence, we obtain the Gagliardo-Nirenberg type inequality and as its application we show global well-posedness of nonlinear PDEs in the noncommutative Euclidean space. Moreover, we show that the logarithmic Sobolev inequality is equivalent to the Nash inequality for possibly different constants in this noncommutative setting by completing the list in noncommutative Varopoulos's theorem in [37]. Finally, we present a direct application of the Nash inequality to compute the time decay for solutions of the heat equation in the noncommutative setting.
