The kernels are obtained as the scaling limits of Christoffel-Uvarov deformations of Jacobi orthogonal polynomial ensembles. %G English %Z The authors are supported by A*MIDEX project(No. ANR-11-IDEX- 0001-02) %Z financed by Programme "Investissements d'Avenir" of the Government of the French Republic managed by the French National Research Agency (ANR) Programme "Investissements d'Avenir" of the Government of the French Republic managed by the French National Research Agency (ANR) %2 https://hal.science/hal-00957661/document %2 https://hal.science/hal-00957661/file/Scaling_limits_of_Christoffel-Uvarov_deformations_of_Jacobi_orthogonal_ensembles.pdf %L hal-00957661 %U https://hal.science/hal-00957661 %~ CNRS %~ UNIV-AMU %~ EC-MARSEILLE %~ I2M %~ I2M-2014- %~ TDS-MACS %~ CERCLE %~ ANR
