Generalized distance to a simplex and a new geometrical method for portfolio optimization
Frédéric Butin
Risk aversion plays a significant and central role in investors' decisions in the process of developing a portfolio. In this framework of portfolio optimization we determine the po…
A bounded operator approach to technical indicators without lag
Frédéric Butin
In the framework of technical analysis for algorithmic trading we use a linear algebra approach in order to define classical technical indicators as bounded operators of the space…
Branching Law for the Finite Subgroups of SL(4,C)
Frédéric Butin
In the framework of McKay correspondence we determine, for every finite subgroup of , how the finite dimensional irreducible representations of $\mathb…
Hochschild Cohomology of Cubic Surfaces
Frédéric Butin
We consider the polynomial algebra and the polynomial , where . Our aim is…
McKay correspondence and the branching law for finite subgroups of
Frédéric Butin, Gadi S. Perets
Given a finite subgroup of , we determine how an arbitrary finite dimensional irreducible representation of decomposes under…
Poisson Homology in Degree 0 for some Rings of Symplectic Invariants
Frédéric Butin
Let $\go{g}$ be a finite-dimensional semi-simple Lie algebra, $\go{h}$ a Cartan subalgebra of $\go{g}$, and its Weyl group. The group acts diagonally on $V:=\go{h}\oplus\go…
