Efficient Numerical Framework for Geothermal Energy Production Optimization in Fracture‐Controlled Reservoirs

International Journal for Numerical Methods in Fluids, Volume 98, Issue 6, Page 709-730, June 2026.
We introduce an efficient open‐source numerical framework for the automated search for the placements of injection and production wells in hot fracture‐controlled reservoirs that sustainably optimize geothermal energy production. We model the reservoirs as discrete fracture networks in 3D. The fluid flow and heat transport in the reservoirs are modeled

On singular Calogero-Moser spaces [PDF]

, 2009
Using combinatorial properties of complex reflection groups, we show that the generalised Calogero-Moser space associated to the centre of the corresponding rational Cherednik algebra is singular for all values of its deformation parameter c if and only ...

Hipercomputación desde la computación cuántica

Revista Colombiana de Computación, 2006
Un hipercomputador computa funciones que son incomputables por una máquina de Turing. Recientemente, Tien D. Kieu ha propuesto un algoritmo hipercomputacional cuántico, el cual emplea como referente físico el oscilador armónico cuántico y resuelve en ...

Quadratic Hedging of American Options Under GARCH Models

Journal of Futures Markets, Volume 46, Issue 6, Page 1079-1097, June 2026.
ABSTRACT American options are widely traded in financial markets, yet there is a scarcity of literature on hedging in incomplete markets. In this paper, we derive optimal hedging ratios and option values using Local Risk Minimization (LRM) and Global Risk Minimization (GRM) hedging strategies through dynamic programming.

Dilation theory for rank two graph algebras. [PDF]

, 2010
An analysis is given of $*$-representations of rank 2 single vertex graphs. We develop dilation theory for the non-selfadjoint algebras $\A_\theta$ and $\A_u$ which are associated with the commutation relation permutation $\theta$ of a 2-graph and, more ...

Sheffer Stroke Hilbert Algebras Stabilizing by Ideals

Axioms
This manuscript aims to provide a new characterization of Sheffer stroke Hilbert algebras due to their ideals and proposes stabilizers. In the setup of the main results, we construct particular subsets of Sheffer stroke Hilbert algebras and we propose ...
