解决LaTeX中\thref触发的Suppressing link with empty target警告

问题原因

该警告源于hyperref与ntheorem的加载顺序错误——ntheorem的thref功能需要先于hyperref完成配置，才能为定理环境生成有效的链接锚点，反之会导致引用时找不到目标，触发空链接警告。

解决步骤

调整包加载顺序：将hyperref移至ntheorem之后加载，确保两者的链接功能正常交互；
保留ntheorem的thref选项：你的代码中已启用[amsmath,thref]选项，这部分无需修改。

    \begin{remark}[Notation: Mode Ordering and Tensor Contraction]\label{rem:MOTC}
        Consider two tensors $A_{ack},B_{dkb}$ then the expressions
        \begin{equation*}
            C_{abcd} = A_{ack}B_{dkb}
        \end{equation*}
        and
        \begin{equation*}
            C_{abcd} = ((A_{ack}(B_{dkb})^{T_{1,2}})^{T_{2,4}})^{T_{3,4}}
        \end{equation*}
        are equivalent.    
    \end{remark}
    The apparent inconsistence can be solved by implying the application of the Transposition Operation, like in \thref{rem:MOTC}.
