We review the construction of the free equations of motion for open and closed strings in 26 dimensions, using the methods of the Florida Group. Differing from previous treatments, we argue that the constraint L0 - 0 = 0 should not be imposed on all the fields of the closed string in the gauge invariant formalism; we show that it can be incorporated in

Singularities in K-space and multi-brane solutions in cubic string field theory
, 2012A bstractIn a previous paper [arXiv:1111.2389], we studied the multi-brane solutions in cubic string field theory by focusing on the topological nature of the “winding number” $ \mathcal{N} $ which counts the number of branes. We found that $ \mathcal{N}

The phantom term in open string field theory
, 2012A bstractWe show that given any two classical solutions in open string field theory and a singular gauge transformation relating them, it is possible to write the second solution as a gauge transformation of the first plus a singular, projector-like ...

Constrained BV description of string field theory
, 2012A bstractIn the conventional BV description of string field theory, the string field Φ is split as Φ = Ψ + Ψ* where Ψ includes all states with ghost number ≤ G and describes the spacetime fields, and Ψ* includes all states with ghost number > G and ...

Thermodynamics of string field theory motivated nonlocal models
, 2012A bstractWe investigate the thermodynamic properties of the nonlocal tachyon motivated by their nonlocal structure in string field theory. We use previously developed perturbative methods for nonlocal fields to calculate the partition function and the ...

Gauge-invariant observables and marginal deformations in open string field theory
, 2012A bstractThe level-truncation analysis of open string field theory for a class of periodic marginal deformations indicates that a branch of solutions in Siegel gauge exists only for a finite range of values of the marginal field.

Homotopy Classification of Bosonic String Field Theory
, 2012We prove the decomposition theorem for the loop homotopy Lie algebra of quantum closed string field theory and use it to show that closed string field theory is unique up to gauge transformations on a given string background and given S-matrix.

Multibrane solutions in open string field theory
, 2011A bstractWe study properties of a class of solutions of open string field theory which depend on a single holomorphic function F (z). We show that the energy of these solutions is well defined and is given by integer multiples of a single D-brane tension.

Winding number in string field theory
, 2011A bstractMotivated by the similarity between cubic string field theory (CSFT) and the Chern-Simons theory in three dimensions, we study the possibility of interpreting $ \mathcal{N} = \left( {{\pi^2}/3} \right)\int {{{\left( {U{\mathcal{Q}_B}{U^{{ - 1}}}}
