We study condensation of closed string tachyons living on defects, such as orbifold fixed planes and Neveu-Schwarz fivebranes. We argue that the high energy density of localized states decreases in the process of condensation of such tachyons. In some cases this means that $c_{eff}$ decreases along the flow; in others, $c_{eff}$ remains constant and the decreasing quantity is a closed string analog, $g_{cl}$, of the ``boundary entropy'' of D-branes. We discuss the non-supersymmetric orbifolds…

We study the condensation of localized closed string tachyons in 3/N nonsupersymmetric noncompact orbifold singularities via renormalization group flows that preserve supersymmetry in the worldsheet

The condensation of closed string tachyons localized at the fixed point of a d/Γ orbifold can be studied in the framework of renormalization group flow in a gauged linear sigma model. The evolution

We find an interesting connection between perturbative large N gauge theory and closed superstrings. The gauge theory in question is found on N D3-branes placed at the tip of the cone 6/Γ. In our

Ricci-flat deformation of orbifolds and localized tachyonic modes

We study Ricci-flat deformations of orbifolds in type II theory. We obtain a simple formula for mass corrections to the twisted modes due to the deformations, and apply it to originally tachyonic and

Closed string tachyons in a smooth curved background

Closed string tachyon condensation has been studied in orbifolds C^2/Z_{N,p} of flat space, using the chiral ring of the underlying N=2 conformal field theory. Here we show that similar phenomena

Condensation of localized tachyons and spacetime supersymmetry

We consider condensation of localized closed string tachyons by examining the recent proposal of Harvey, Kutasov, Martinec, and Moore. We first observe that the gcl defined by HKMM does not reflect

M-theory lift of brane-antibrane systems and localised closed string tachyons

We discuss the lift of certain D6-D6-brane systems to M-theory. These are purely gravitational conflgurations with a bolt singularity. When reduced along a trivial circle, and for large bolt radius,

Off-shell interactions for closed-string tachyons

Off-shell interactions for localized closed-string tachyons in C/Z{sub N} superstring backgrounds are analyzed and a conjecture for the effective height of the tachyon potential is elaborated. At

Closed string tachyon condensation on twisted circles

We study IIA/B string theory compactified on twisted circles. These models possess closed string tachyons and reduce to type-0B/A theory in a special limit. Using methods of gauged linear sigma
