Description
We study the system of M2-branes suspended between parallel M5-branes
using ABJM model with a natural half-BPS boundary condition. For small
separation between M5-branes, the worldvolume theory is shown to
reduce to a 2D N=(4,4) super Yang-Mills theory with some similarity to
q-deformed Yang-Mills theory. The gauge coupling is related to the
position of the branes in an interesting manner. The theory is
considerably different from the 2D theory proposed for multiple
"M-strings". We make a detailed comparison of elliptic genus of the
two descriptions and find only a partial agreement.
