We study the evolution of stable D-branes of C/Z_n and twisted circletheories in the process of closed string tachyon condensation. We interpret thefractional branes in these backgrounds as type II branes wrapping (`blown up')cycles, and trace the evolution of the corresponding cycles under tachyoncondensation. We also study RG flows of the corresponding N=2 boundaryconformal field theories. We find flows along which fractional D-branes eitherdisappear or evolve into other fractional D-branes, and other flows along whichbulk branes either disappear or evolve into stable branes.Comment: 38 pages plus appendices, 9 figures, Harvma
