Subspace gradient descent method for linear tensor equations
Martina Iannacito, Lorenzo Piccinini, Valeria Simoncini
The numerical solution of algebraic tensor equations is a largely open and challenging task. Assuming that the operator is symmetric and positive definite, we propose two new gradi…

Monotonicity, bounds and extrapolation of Block-Gauss and Gauss-Radau quadrature for computing
Jörn Zimmerling, Vladimir Druskin, Valeria Simoncini
In this paper, we explore quadratures for the evaluation of where is a symmetric positive-definite (s.p.d.) matrix in , is a tall mat…
