Vanna-Volga pricing for single and double barrier FX options

J. Martín Ovejero

In this paper, we provide a unified treatment of the Vanna-Volga pricing technique. We derive the value of single and double barriers FX options, as well as closed formulas for the…

On the subalgebra of invariant elements: finiteness and immersions

Jesús Martín Ovejero, Ángel Luis Muñoz Castañeda, Francisco José Plaza Martín

Let $R$ be an algebra over a ring $k$ , $T$ an $R$ -algebra, $M$ a finitely generated projective $R$ -module, and $N$ a $T$ -module. Let $G$ be a linearly reductive group scheme ov…

Coordinate rings of some $S L_{2}$ -character varieties

Vicente Muñoz, Jesús Martín Ovejero

We determine generators of the coordinate ring of $S L_{2}$ -character varieties. In the case of the free group $F_{3}$ we obtain an explicit equation of the $S L_{2}$ -character variety. Fo…
