On the r-uniform linear hypertrees with extremal Estrada indices

作者：

Highlights：

• Several new transformations for studying the Estrada indices of hypergraphs are introduced.

• The hypertrees with the smallest, the second smallest, the largest, and the second largest Estrada indices are derive.
