Abstract:
In the work studied curves of negative selfintersection on algebraic surfaces. It's showed that there exist smooth complex projective surfaces $X$, such that $X$ contains reduced, irreducible curves of arbitrary negative selfintersection. Also there is considered other related questions about lower bounds of selfintersection of curves on algebraic surfaces.
