Descent via Koszul extensions
Lars Winther Christensen, Sean Sather-Wagstaff
Let R be a commutative noetherian local ring with completion R^. We apply differential graded (DG) algebra techniques to study descent of modules and complexes from R^ to R' where…
On moment-density estimation in some biased models
Robert M. Mnatsakanov, Frits H. Ruymgaart
This paper concerns estimating a probability density function based on iid observations from , where the weight function and the total weight $W=\int…
The generalized-Euler-constant function and a generalization of Somos's quadratic recurrence constant
Jonathan Sondow, Petros Hadjicostas
We define the generalized-Euler-constant function when . Its values include both Euler's constant $γ=…
Comparison of Two Scale-Dependent Dynamic Subgrid-Scale Models for Simulations of Neutrally Buoyant Shear-Driven Atmospheric Boundary Layer Flows
William Anderson, Sukanta Basu, Chris Letchford
A new scale-dependent dynamic subgrid-scale (SGS) model based on Kolmogorov's scaling hypothesis is presented. This SGS model is utilized in large-eddy simulation of a well-known c…
