Comparing GL n -representations by characteristic-free isomorphisms between generalized Schur algebras
Comparing GL n -representations by characteristic-free isomorphisms between generalized Schur algebras
Isomorphisms are constructed between generalized Schur algebras in different degrees. The construction covers both the classical case (of general linear groups over infinite fields of arbitrary characteristic) and the quantized case (in type A , for any non-zero value of the quantum parameter q ). The construction does not depend …
