 On Wednesday, March 17, 11am - 12am Room C (SISSA Mb)


              Prof. Dorothea Bahns
           (University of Goettingen)

 will deliver a seminar on

     The Shuffle Algebra and String Quantization in d dimensions.

 Abstract: I will review a purely algebraic approach to the quantization
 of strings, e.g. minimal surfaces, based on the deformation of a certain
 Poisson algebra. The elements of this algebra are invariant under
 changes of the string's parametrization and the formalism is consistent
 in any dimension of the embedding space. This is in contrast to the
 ordinary approach to string quantization which is based on methods from
 conformal field theory and requires fixing the dimension to a critical
 value (26 in the model discussed in the talk).
