Several invariants are attached to automorphic forms on algebraic groups. These invariants and relationships between them are very useful for studying the internal structure of automorphic forms. In this research, we investigated relationships between these invariants for automorphic forms of special kind called Aarkawa liftings. Using this result, we proposed certain conjectures on relations between invariants attached to automorphic forms on certain groups. We showed that automorphic forms called Borcherds products have strong symmetries (the multiplicative symmetries). We also studied the Borcherds products in detail in the genus two Siegel modular case. In particular, we obtained several results about the weights and characters of Borcherds products.

几个不变量被附加到代数群上的自同构形式。这些不变量及其之间的关系对于研究自同构形的内部结构是非常有用的。在这项研究中，我们研究了被称为Aarkawa提升的特殊类型的自同构形式的这些不变量之间的关系。利用这一结果，我们对某些群上依附于自同构型的不变量之间的关系提出了某些猜想。我们证明了自同构形式称为Borcherd积具有强对称性(乘法对称性)。我们还详细地研究了亏格为2的Siegel模壳中的Borcherd积。特别地，我们得到了关于Borcherd积的重量和特征的几个结果。
