Idea
A string is a brane of dimension one higher than an ordinary particle :
where a 1-dimensional sigma-model may be thought of a describing the dynamics of particle s propagating of a target space X X , a 2-dimensional sigma-model is said to described the dynamics of a string on some target space.
Much of traditional quantum field theory on X X may be understood in terms of second quantization of 1-dimensional sigma-models with target space X X . What is called string theory is the corresponding study of what happens to this situation as the 1-dimensional σ \sigma -model is replaced by a 2-dimensional one.
