1. Commutative geometry for non-commutative D-branes by tachyon condensation / Asakawa, Tsuguhiko ; Ishiki, Goro ; Matsumoto, Takaki ; Matsuura, So ; et al
There is a difficulty in defining the positions of the D-branes when the scalar fields on them are non-Abelian. [...]

3. O(a) improvement of 2D N=(2,2) lattice SYM theory / Hanada, Masanori ; Kadoh, Daisuke ; Matsuura, So ; Sugino, Fumihiko
We perform a tree-level O(a) improvement of two-dimensional N=(2,2) supersymmetric Yang–Mills theory on the lattice, motivated by the fast convergence in numerical simulations. [...]

As a perturbative check of the construction of 4D supersymmetric Yang–Mills theory (SYM) from mass-deformed SYM on the 2D lattice, the one-loop effective action for scalar kinetic terms is computed in SYM on (fuzzy ), which is obtained by expanding 2D SYM with mass deformation around its fuzzy-sphere classical solution.
