On R-matrix valued Lax pairs for Calogero–Moser models

Abstract: The article is devoted to the study of R-matrix-valued Lax pairs for N -body (elliptic) Calogero-Moser models. Their matrix elements are given by quantum GLÑ R-matrices of Baxter-Belavin type. ForÑ = 1 the widely known Krichever's Lax pair with spectral parameter is reproduced. First, we construct the R-matrix-valued Lax pairs for Calogero-Moser models associated with classical root systems. For this purpose we study generalizations of the D'Hoker-Phong Lax pairs. It appeared that in the R-matrix-valued case t… Show more

“…Applications of the obtained models are related to the so-called R-matrix-valued Lax pairs for the (classical) spinless Calogero-Moser model [20,29,14]. These are the Lax pairs in a large space Mat(M, C) ⊗ Mat(N, C) ⊗M :…”

“…Для некоторых других систем корней R-матричные пары Лакса описаны в работах [8], [16]. Пространство Mat(n, C) мы будем называть вспомогательным и обозначать индексом "aux" (от слова auxiliary), а пространство Mat(N n , C), в котором лежит любой из блоков, -квантовым в том смысле, что оно совпадает с End(H), где H ∼ = (C N ) ⊗n -гильбертово пространство квантовой спиновой GL(N, C)-цепочки, содержащей n узлов (в фундаментальном представлении группы GL(N, C)).…”
