Tīmeklis2010. gada 16. dec. · Rational curves on K3 surfaces. We show that projective K3 surfaces with odd Picard rank contain infinitely many rational curves. Our proof … Tīmeklis1997. gada 30. janv. · The aim of these notes is to explain the remarkable formula found by Yau and Zaslow to express the number of rational curves on a K3 surface. Projective K3 surfaces fall into countably many families F (g) (g>0); a surface in F (g) admits a g-dimensional linear system of curves of genus g.

Tīmeklis2024. gada 24. sept. · Because k strongly depends on T, precise control over the reactor temperature is critical in industrial processes. For an open system in which both mass and heat can be exchanged with the surroundings, we can write the energy balance of of the system as (1.23.22) d E d t = d Q d t + D W d t + ∑ j ( F j (in) E j (in) − F j (out) E j … Tīmeklisfor which we seek integral or rational solutions.
