dc.description.abstract在我和老師的會議中,認為型態(C1∨, C1)的通用加法DAHA中能看到Leonard三元組,所以我們利用學術網站上的相關論文,並且透過通用 Racah代數來得到以下結果。 假設 ? 是一個特徵為零的代數封閉體。通用Racah代數R是由A,B,C,D生成的單位結合?-代數,關係式為 [A, B] = [B, C] = [C, A] = 2D 並且每個 [A, D] + AC − BA, [B, D] + BA − CB, [C, D] + CB – AC 在R上皆可換。 型態 (C1∨, C1) 的通用加法 DAHA (雙仿射 Hecke 代數)H是由 t_0,t_1,t_2,t_3 生成的單位結合 ?-代數,關係式為 t_0+t_1+t_2+t_3= -1, t_0^2, t_1^2, t_2^2, t_3^2 皆可換。 任何H-module 都可以被認為是一個R-module 透過 ?-代數同態將 送到H,由下式給出 A 送到 (t_0+t_1-1)(t_0+t_1+1)/4, B 送到 (t_0+t_2-1)(t_0+t_2+1)/4, C 送到 (t_0+t_3-1)(t_0+t_3+1)/4。 令 V 表示有限維不可分 H-module。 在本文中,我們展示了 A, B, C 在 V 上可對角化若且為若 A, B, C 在 R-module V 的所有合成因子上為Leonard 三元組。zh_TW
dc.description.abstractIn the meeting, I thought that the Leonard triples can be seen in the universal additive DAHA of type (C1∨, C1), so we used the relevant papers on the academic website and obtained the following results through the universal Racah algebra. Suppose that ? is an algebraically closed field with characteristic 0. The universal Racah algebra R is a unital associative ?-algebra generated by A, B, C, D and the relations state that [A, B] = [B, C] = [C, A] = 2D and each of [A, D] + AC - BA, [B, D] + BA - CB, [C, D] + CB - AC is central in R. The universal additive DAHA (double affine Hecke algebra) H of type (C1∨, C1) is a unital associative ?-algebra generated by t_i (i=0,1,2,3) and the relations state that t_0+t_1+t_2+t_3= -1, t_i^2 is central for all i = 0, 1, 2, 3. Any H-module can be considered as a R-module via the ?-algebra homomorphism R to H given by A mapsto (t_0+t_1-1)(t_0+t_1+1)/4, B mapsto (t_0+t_2-1)(t_0+t_2+1)/4, C mapsto (t_0+t_3-1)(t_0+t_3+1)/4. Let V be a finite-dimensional irreducible H-module. In this paper we show that A, B, C are diagonalizable on V if and only if A, B, C act as Leonard triples on each composition factor of the R-module V.en_US
