Abstract: We introduce a construction adding low-dimensional cells to a space that satisfies certain low-dimensional conditions; it preserves high-dimensional homology with appropriate coefficients. T...

Using a bidifferential graded algebra approach to integrable partial differential or difference equations, a unified treatment of continuous, semi-discrete (Ablowitz-Ladik) and fully discrete matrix N...
To tackle multi collinearity or ill-conditioned designmatrices in linear models, adaptive biased estimators such as thetime-honored Stein estimator, the ridge and the principalcomponent estimators hav...
