We study the remnants of Yangian symmetry of AdS/CFT magnons reflecting from boundaries with no degrees of freedom. We present the generalized twisted boundary Yangian of open strings ending on boundaries which preserve only a subalgebra \mathfrakh Unknown control sequence '\mathfrak'of the bulk algebra \mathfrakg Unknown control sequence '\mathfrak', where ( \mathfrakg,\mathfrakh ) Unknown control sequence '\mathfrak'is a symmetric pair. This is realized by open strings ending on the D3 brane known as the Y = 0 maximal giant graviton in AdS 5 × S 5. We also consider the Yangian symmetry of the boundary which preserves an \mathfraks\mathfraku( 1 |2 ) Unknown control sequence '\mathfrak'subalgebra only.
