Unitary involutions on a simple central algebra after a scalar extension
Then we know that there exist unitary $L/K$-involutions on $A$ (i.e. involutions of the second kind leaving $K$ element-wise invariant). … In "The Book of Involutions" by Knus, Merkurjev, Rost and Tignol, I found (3.17) and (3.19) giving a correspondence between unitary $L/K$-involutions on $A$ and the right ideals $I\subset N_{L/K}(A)$ …
