  • Bonelli, Giulio; Bonora, Loriano; Ricco, Antonio (2005)
    This paper is a continuation of hepth/0507224 where open topological B-models describing D-branes on 2-cycles of local Calabi--Yau geometries with conical singularities were studied. After a short review, the paper expands ...
  • Bonelli, Giulio; Bonora, Loriano; Ricco, Antonio (2005)
    We study open B-model representing D-branes on 2-cycles of local Calabi-Yau geometries. To this end we work out a reduction technique linking D-branes partition functions and multimatrix models in the case of conifold ...
  • Bonelli, Giulio; Bonora, Loriano; Ricco, Antonio (2006-04-18)
    In this letter we study topological open string field theory on D--branes in a IIB background given by non compact CY geometries ${\cal O}(n)\oplus{\cal O}(-2-n)$ on $\P1$ with a singular point at which an extra fiber sits. ...
  • Bruzzo, Ugo; Ricco, Antonio (2005)
    We prove a conjecture by F. Ferrari. Let X be the total space of a nonlinear deformation of a rank 2 holomorphic vector bundle on a smooth rational curve, such that X has trivial canonical bundle and has sections. Then the ...
