In both cases, we characterize the possible limit\r\nfunctions and the Vershik-Kerov type sequences of spectral parameters for which\r\nsuch limits exist. In the type $A$ case, this gives a new and very natural\r\napproach to recent results by Assiotis and Najnudel in the context of\r\n$\\beta$-ensembles in random matrix theory. These results generalize known facts\r\nabout the approximation of the (positive-definite) Olshanski spherical\r\nfunctions of the space of infinite-dimensional Hermitian matrices over $\\mathbb\r\nF = \\mathbb R, \\mathbb C, \\mathbb H$ (with the action of the associated\r\ninfinite unitary group) by spherical functions of finite-dimensional spaces of\r\nHermitian matrices. In the type B case, our results include asymptotic results\r\nfor the spherical functions associated with the Cartan motion groups of\r\nnon-compact Grassmannians as the rank goes to infinity, and a classification of\r\nthe Olshanski spherical functions of the associated inductive limits.","lang":"eng"}],"publisher":"Elsevier"}
