Sazetak:

The AdS/CFT correspondence provides an interesting relation
between particular gauge and string theories. Its canonical example is the
duality between string theory in AdS5xS5 and four dimensional N=4
supersymmetric Yang-Mills theory. As it turns out, the string in AdS5xS5 is
special (integrable), which makes it possible to nonperturbatively compute
observables in supersymmetric Yang-Mills theory in the so-called planar
limit. I will explain what integrability is, how it can be used to describe
the string, and how this gives results in supersymmetric Yang-Mills theory.
Building on this, I will describe deformations of the string on AdS5xS5 that
are constructed to preserve its integrability, and explain that the
corresponding deformation of supersymmetric Yang-Mills theory lies in the
realm of noncommutative field theory, including noncommutativity of
kappa-Minkowski type. Time permitting, I will also deform the string in
Minkowski space to realize kappa-Poincaré symmetry, which will turn out to
relate to earlier parts of my talk in an interesting way.
