λ-calculus in an algebraic setting
, 2006 We define an extension of λ-calculus with linear combinations of terms, with coefficients taken in a fixed rig R. We extend β-reduction on these terms as follows: at + u reduces to at ′ + u as soon as term t reduces to t ′ and a is a non-zero scalar.

"On Approximation of the Solutions to Partial Differential Equations in Finance" [PDF]
This paper proposes a general approximation method for the solutions to second-order parabolic partial differential equations (PDEs) widely used in finance through an extension of Léandre's approach(Léandre (2006,2008)) and the Bismut identiy(e.g ...

International audienceWe introduce a variant of the algebraic λ-calculus, which extends the ordinary λ-calculus with the possibility of forming linear combinations of terms, with coefficients taken in a fixed semiring.

Some properties of general-$λ$-matrix polynomials: an umbral approach
The 2-variable general-$λ$-matrix polynomials (2VG$λ$MP) is a new family of matrix polynomials, introduced and studied in this article. These matrix polynomials are constructed using umbral and symbolic methods.
