Journal of Low Frequency Noise, Vibration and Active Control, 2018 The partial eigenvalue (or natural frequency) assignment or placement, only by the stiffness matrix perturbation, of an undamped vibrating system is addressed in this paper. A novel and explicit formula of determining the perturbating stiffness matrix is

On Some Applications of Matrix Partial Orders in Statistics [PDF]
International Journal of Management, Knowledge and Learning, 2020 In statistics different partial orders appear as useful in several cases. Three of the best known partial orders defined on (sub)sets of real or complex matrices are the Löwner, the minus and the star partial orders.

Phase diagrams for two-component D-wave fermion superfluids with density imbalance
New Journal of Physics, 2022 Finite-temperature phase structures for asymmetric two-component D -wave fermion superfluids in the weak coupling BCS regime are investigated. The Fulde–Ferrell–Larkin-Ovchinnikov (FFLO) state becomes non-degenerate with the orientation of Cooper pair ...

Partial Permutation and Alternating Sign Matrix Polytopes
SIAM Journal on Discrete Mathematics, 2022 We define and study a new family of polytopes which are formed as convex hulls of partial alternating sign matrices. We determine the inequality descriptions, number of facets, and face lattices of these polytopes. We also study partial permutohedra that we show arise naturally as projections of these polytopes.

Eigenstate Correlations in Dual-Unitary Quantum Circuits: Partial Spectral Form Factor [PDF]
QuantumWhile the notion of quantum chaos is tied to random matrix spectral correlations, also eigenstate properties in chaotic systems are often assumed to be described by random matrix theory.

Finding Structure with Randomness: Probabilistic Algorithms for Constructing Approximate Matrix Decompositions [PDF]
SIAM Review, 2009 Low-rank matrix approximations, such as the truncated singular value decomposition and the rank-revealing QR decomposition, play a central role in data analysis and scientific computing.

SpArch: Efficient Architecture for Sparse Matrix Multiplication [PDF]
International Symposium on High-Performance Computer Architecture, 2020 Generalized Sparse Matrix-Matrix Multiplication (SpGEMM) is a ubiquitous task in various engineering and scientific applications. However, inner product based SpGEMM introduces redundant input fetches for mismatched nonzero operands, while outer product ...

Partial compositeness and baryon matrix elements on the lattice [PDF]
Physical Review D, 2018 Partial compositeness is a mechanism for the generation of fermion masses which replaces a direct Higgs coupling to the fermions by a linear mixing with heavy composite partners.
