Query: The surgery exact triangle in Pin(2)-monopole Floer homology   We prove the existence of an exact triangle for the Pin(2)-monopole Floer
homology groups of three manifolds related by specific Dehn surgeries on a
given knot. Unlike the counterpart in usual monopole Floer homology, only two
of the three maps are those induced by the corresponding elementary cobordism.
We use this triangle to describe the invariants associated to homology spheres
obtained by (\pm1)-surgery on alternating knots.
