\textbf{תקציר:}
  Abstract. In 1980s Goldman introduced a Lie algebra structure on
the free vector space generated by the free homotopy classes of oriented
closed curves in any orientable surface F. This Lie bracket is known as
the Goldman bracket and the Lie algebra is known as the Goldman Lie
algebra.
In this talk I will discuss some basic properties of Goldman bracket
and its relation with Teichmüller space. I will also show how techniques
from geometric group theory could be used to compute center of the
Goldman Lie algebra. I will mention some open problems related to
Goldman bracket.
