有限群G的有限维模表示M的核是它的最大非投射和项。证明了当M是Ω-代数时,M_n的核的维数具有代数Hilbert级数,即M_n的非投射和子在合冲算子Ω的作用下落入n个轨道.同样,我们证明了当M是Ω+-代数时,这些维数序列最终是线性递归的。这部分回答了Benson和Symonds的一个猜想。沿着这条路,我们还证明了多变量序列上线性常返算子的一些辅助持久性结果。
The core of a finite-dimensional modular representation M of a finite group G is its largest non-projective summand. We prove that the dimensions of the cores of M⊗ n have algebraic Hilbert series when M is Omega-algebraic, in the sense that the non-projective summands of M⊗ n fall into finitely many orbits under the action of the syzygy operator Ω. Similarly, we prove that these dimension sequences are eventually linearly recursive when M is what we term Ω+-algebraic. This partially answers a conjecture by Benson and Symonds. Along the way, we also prove a number of auxiliary permanence results for linear recurrence under operations on multi-variable sequences.
