Decomposition numbers for generic Iwahori-Hecke algebras of noncrystallographic type
The author computes (with the aid of some computer algebra systems such as GAP, CHEVIE,\dots etc.) the \(\varphi_e\)-modular decomposition matrices for the generic Iwahori-Hecke algebra of type \(I_2(m)\) for \(m\in\mathbb{N}\), \(m>2\), \(H_3\) and \(H_4\) for all \(e\in\mathbb{N}\) leading to non-trivial decomposition maps.
