Linear Systems of Rational Curves on Rational Surfaces [PDF]
Moscow Mathematical Journal, 2012 Given a curve C on a projective nonsingular rational surface S, over an algebraically closed field of characteristic zero, we are interested in the set Omega_C of linear systems Lambda on S satisfying C is in Lambda, dim Lambda > 0, and the general member of Lambda is a rational curve.

Arcs and wedges on rational surface singularities [PDF]
, 2011 Given a rational surface singularity (S,P0) over an algebraically closed field of characteristic 0, we prove that its minimal desingularization satisfies the property of lifting wedges centered at those stable points Pα of the space of arcs S∞ which ...

Monotone Data Visualization Using Rational Trigonometric Spline Interpolation
The Scientific World Journal, 2014 Rational cubic and bicubic trigonometric schemes are developed to conserve monotonicity of curve and surface data, respectively. The rational cubic function has four parameters in each subinterval, while the rational bicubic partially blended function ...

Rational rolling ball blending of natural quadrics
Mathematical Modelling and Analysis, 2000 We construct a blending surface of two natural quadrics using rational variable rolling ball approach, i.e. as a canal surface with a rational spine curve and a rational radius. All general positions of the given quadric surfaces are considered.

On the measurable dynamics of real rational functions [PDF]
, 2003 Let f be a real rational function with all critical points on the extended real axis and of even order. Then: (1) f carries no invariant line field on the Julia set unless it is doubly covered by an integral torus endomorphism (a Lattés example); and

Optimal bound for the number of (−1)-curves on extremal rational surfaces
International Journal of Mathematics and Mathematical Sciences, 2002 We give an optimal bound for the number of (−1)-curves on an extremal rational surface X under the assumption that −KX is numerically effective and having self-intersection zero.
