DESCRIPTION:ROBERT GARBARY\, PURE MATHEMATICS\, UNIVERSITY OF WATERLOO\n\n\
 "LOCAL POSITIVITY OF LINE BUNDLES ON TORIC SURFACES\"\n\nLet $X$ be a smoo
 th algebraic variety\, and let $p \\in X$. Let $\\pi :\n\\tilde{X} \\to X$
  denote the blow-up of $X$ at $p$ with exceptional\ndivisor $E$. Given an 
 effective divisor $L$ on $X$\, we define\n$\\gamma_p(L) = \\sup \\{ t \\ge
 q 0 : \\pi^*L - tE \\text{ is effective}\n\\}$. In this thesis\, we develo
 p the theory of this number.
