Abstract:We consider a circular, bounded, strictly convex domain $ \Omega\subset\mathbb{C}^{d}$ with boundary of class $ C^{2}$. For any compact subset $ K$ of $ \partial\Omega$ we construct a sequence of homogeneous polynomials on $ \Omega$ which are big at each point of $ K$. As an application for any $ E\subset\partial\Omega$ circular subset of type $ G_{\delta}$ we construct a holomorphic function $ f$ which is square integrable on $ \Omega\setminus\mathbb{D}E$ and such that $ E=E_{\Omega}^{2}(f):=\left\{z\in\partial\Omega: \int_{\mathbb{D}z}\left\vert f\right\vert^{2}d\mathfrak{L}_{\mathbb{D}z}^{2} =\infty\right\} $ where $ \mathbb{D}$ denotes unit disc in $ \mathbb{C}$.

Keywords:homogeneous polynomials  exceptional sets  highly nonintegrable holomorphic function
