Massive states of bosonic strings
, 2008 Some basic properties of the bosonic string theory are discussed. First the classical string theory is discussed and two different methods to quantise, the covariant approach and the light-cone gauge approach. Using the covariant approach one can get the

Automorphisms and twisted vertex operators [PDF]
, 1987 This work is an examination of various aspects of twisted vertex operator representations of Kac-Moody algebras. It starts with an introduction to Kac-Moody algebras and string theories, including a discussion of the propagation of strings on orbifolds ...

The Fokker-Planck formalism for closed bosonic strings
, 2023 Every Riemann surface with genus $g$ and $n$ punctures admits a hyperbolic metric, if $2g-2+n>0$. Such a surface can be decomposed into pairs of pants whose boundaries are geodesics.

Modular transformations of admissible N = 2 and Affine sl(2|1;C) characters [PDF]
, 2002 This thesis is a study of the affine super-algebra sl(2|l; C) and N = 2 superconformal algebra at fractional levels. In the first chapter we review background material on Conformal Field Theory, and how it appears in the context of string theory and the ...

The topological renormalisation of the 0(3) sigma model [PDF]
, 1995 Like other field theories of physical interest, the moduli-space integrals of the non-linear two-dimensional 0(3) sigma model diverge. We show that in the one-instanton sector the imposition of a cut-off in the moduli-space leads to an unacceptable ...

The effect of dark strings on semilocal strings [PDF]
, 2009 peer reviewedDark strings have recently been suggested to exist in new models of dark matter that explain the excessive electronic production in the Galaxy.

Introduction to strings and branes
, 2012 Supersymmetry, strings and branes are believed to be the essential ingredients in a single unified consistent theory of physics. This book gives a detailed, step-by-step introduction to the theoretical foundations required for research in strings and ...

Dual Peierls brackets for strings
, 1987 A new type of Peierls bracket which provides an additional representation of the Virasoro algebra, and which may be of relevance for a manifestly dual string field theory is constructed for the closed and open bosonic ...

Giant Magnons and Giant Gravitons [PDF]
, 2011 In this thesis we shall present work concerning the description of the emergence of solitonic fundamental strings from stable, finite energy, compact D3-branes in a subspace of $AdS_{5}\times S^{5}$ and their subsequent interaction.

Dilation condensates and loop effects in open and closed bosonic strings
, 1987 Consistent string propagation in general backgrounds requires conformal invariance. At the tree level, this requires Gell- Mann-Low β functions for the geometric couplings to vanish.
