The M5-branes are magnetically dual cousins of M2-branes. But writing
down an interacting field theory for multiple M5-branes has remained
an elusive goal so far. Recent constructions of various membrane
theories, such as ABJM and BLG Chern-Simons matter theories, has led
to some understanding that gauge-fields are the vital building blocks
in M-theory as well. I shall present an unique way to uplift the
cosmetic structure of 5D SYM to a 6-dimensional framework. The new
6-dimensional theory acquires scale invariance.
