Projection-based low-rank assembly in IgA

Numerical experiments show that the projection-based low-rank approach for assembling the mass and stiffness tensors of orientation-preserving tensor-product B-spline geometries is competitive with full assembly and with the interpolation-based low-rank method, and that it applies in two situations in which interpolati...

Adaptive Krylov Methods for Low-Rank Exponential Integrators

KIOPS-TT and RK2EXPINT-TT are developed as extensions of the original KIOPS and RK2EXPINT algorithms, reformulating the scheme of explicit exponential Runge-Kutta integrators for tensors and augmenting the stiffness tensor to compute linear combinations of $\varphi$-functions acting on tensors through a single evaluati...
