Abstract: We consider the problem of bounding the dimension of the linear system of curves in $ \mathbf{P}^2$ of degree $ d$ with prescribed multiplicities $ m_1,\dots,m_n$ at $ n$ general points (Harbourne (1986), Hirschowitz (1985)). We propose a new method, based on the work of Ciliberto and Miranda (2000, 2003), by specializing the general points to an elliptic curve in $ \mathbf{P}^2$.
