Query: Brunnian exotic surface links in the 4-ball   This paper investigates the exotic phenomena exhibited by links of
disconnected surfaces with boundary that are properly embedded in the 4-ball.
Our main results provide two different constructions of exotic pairs of surface
links that are Brunnian, meaning that all proper sublinks of the surface are
trivial. We then modify these core constructions to vary the number of
components in the exotic links, the genera of the components, and the number of
components that must be removed before the surfaces become unlinked. Our
arguments extend two tools from 3-dimensional knot theory into the
4-dimensional setting: satellite operations, especially Bing doubling, and
covering links in branched covers.
