Holonomies of gauge fields in twistor space 1: bialgebra, supersymmetry, and gluon amplitudes
Yasuhiro Abe
We introduce a notion of holonomy in twistor space and construct a holonomy operator by use of a spinor-momenta formalism in twistor space. The holonomy operator gives a monodromy…
An interpretation of multigraviton amplitudes
Yasuhiro Abe
We obtain alternative expressions for the multigraviton tree level amplitudes and discuss their general properties. In particular, by analogy with Yang-Mills theory, we find that s…
Multigluon amplitudes, constraints and the WZW model
Yasuhiro Abe, V. P. Nair, Mu-In Park
Classical Yang-Mills theory is defined by the superspace constraints. We obtain a solution of a subset of these constraints and show that it leads to the maximally hel…
Construction of fuzzy S^4
Yasuhiro Abe
We construct a fuzzy , utilizing the fact that is an bundle over . We find that a fuzzy can be described by a block-diagonal form whose embedding…
Noncommutative gravity: fuzzy sphere and others
Yasuhiro Abe, V. P. Nair
Gravity on noncommutative analogues of compact spaces can give a finite mode truncation of ordinary commutative gravity. We obtain the actions for gravity on the noncommutative two…
