我们在抽象Keel–Tao框架下建立了正交Strichartz估计，所用假设与该原始定理完全一致。作为重要推论，我们解决了维度d≥2时薛定谔方程的端点猜想，该猜想最初由Frank、Lewin、Lieb和Seiringer提出。此推论还为自由传输方程的对应猜想给出了肯定答案，该猜想由Bennett、Bez、Gutiérrez和Lee以对偶形式表述。作为进一步应用，我们还建立了针对单个函数的Strichartz估计的改进形式。
英文摘要
We establish the orthonormal Strichartz estimates in the abstract Keel--Tao framework, under precisely the same hypotheses as in their original theorem. As an important consequence, we resolve the endpoint conjecture for the Schrödinger equation in dimensions $d\ge 2$, which was first raised by Frank, Lewin, Lieb, and Seiringer. This consequence also yields an affirmative answer to the conjecture for the free transport equation, which was stated in dual form by Bennett, Bez, Gutiérrez, and Lee. As a further application, we also establish a refinement of the Strichartz estimate for a single function.
