有限性猜想在SL(2,Z>=0)^2中成立
The finiteness conjecture holds in SL(2,Z>=0)^2
摘要:
设A,B是SL(2,R)中迹大于或等于2的矩阵.假设对A,B是相干定向的,也就是说,可以共轭到具有非负项的对。还假设A、B^(-1)也是相干定向的,或者A、B具有整数项。然后Lagarias-Wang有限性猜想对集合{A,B}成立,最优乘积在{A,B,AB,A^2B,AB^2}中。特别地,它对SL(2,Z>=0)中的每个矩阵对都成立。
英文摘要:
Let A,B be matrices in SL(2,R) having trace greater than or equal to 2. Assume the pair A,B is coherently oriented, that is, can be conjugated to a pair having nonnegative entries. Assume also that either A,B^(-1) is coherently oriented as well, or A,B have integer entries. Then the Lagarias-Wang finiteness conjecture holds for the set {A,B}, with optimal product in {A,B,AB,A^2B,AB^2}. In particular, it holds for every matrix pair in SL(2,Z>=0).
