Affine supersymmetric pairs
Andrey Mudrov, Vladimir Stukopin
We classify Satake diagrams for general linear and orthosymplectic non-twisted affine Lie superalgebras and prove that each of them generates a family of proper spherical subalgebr…

Graded Satake diagrams and super-symmetric pairs
D. Algethami, A. Mudrov, V. Stukopin
We list classical spherical subalgebras in basic matrix Lie superalgebras which are quantizable to coideal subalgebras in the standard quantum supergroups, for any choice of Borel…
