Nonlinear power-like iteration by polar decomposition and its application to tensor approximation

NUMERISCHE MATHEMATIK, 144(4), 729–749.

Contributors: B. Dong*, N. Jiang* & M. Chu n

TL;DR: This paper proposes a scheme similar to the power method for subspace iterations except that the polar decomposition is used as the normalization process and that the iteration can be applied to both the orbits and the cross-sections. (via Semantic Scholar)

Variance-based sensitivity analysis for time-dependent processes

RELIABILITY ENGINEERING & SYSTEM SAFETY, 196.

author keywords: Global sensitivity analysis; Sobol' Indices; Karhunen-Loeve expansion; Time-dependent processes; Surrogate models; Polynomial chaos; Uncertainty quantification
TL;DR: A variance-based method is developed that leverages the correlation structure of the problems under study and employs surrogate models to accelerate the computations and analyzes errors resulting from fixing unimportant uncertain parameters to their nominal values through a priori estimates.

Differential Signatures of Algebraic Curves

SIAM Journal on Applied Algebra and Geometry.

By: I. Kogan*, M. Ruddy & C. Vinzant

author keywords: algebraic curves; projective action; affine action; Euclidean action; equivalence classes of curves; differential invariants; classifying invariants; signatures; Fermat curves
TL;DR: The differential signature construction is adapted to the equivalence problem for complex plane algebraic curves under the actions of the projective group and its subgroups and it is proved that for any $G$-action, there exists a pair of rational differential invariants, called classifying invariant, that can be used to construct signatures.
