| Research Abstract |
We studied the M-brane in M-theory which can be considered as a unification of various D-branes in string theories. We constructed the M5-branes from M2-branes and showed that the 3-algebra, which is a generalization of Lie algebra, is important for M-branes. Because the noncommutative geometry appears in D-brane physics is related to the Lie algebra, this result suggests that there is generalized geometry based on the 3-algebra and it is important to the M-theory.
