Abstract Motivated by previous research on the osculation for special varieties, we investigate rational conic fibrations in connection with their enveloping projective bundles with the aim of comparing their inflectional loci. Specific existence results for such pairs are established. As a consequence, the possible various numerical characters of the pairs involved for low values of the sectional genus are determined.

包络理性圆锥纤维和密切关系的射影丛

摘要 受先前对特殊品种的密切关系研究的启发，我们研究了与包络射束相关的合理圆锥纤维，目的是比较它们的屈折轨迹。建立这种对的具体存在结果。因此，确定了部分属的低值所涉及的对的可能的各种数字特征。
