Quantum-embeddable stochastic matrices [PDF]

open access: yesQuantum
The classical embeddability problem asks whether a given stochastic matrix $T$, describing transition probabilities of a $d$-level system, can arise from the underlying homogeneous continuous-time Markov process.

Construction of 4 x 4 symmetric stochastic matrices with given spectra

open access: yesOpen Mathematics
The symmetric stochastic inverse eigenvalue problem (SSIEP) asks which lists of real numbers occur as the spectra of symmetric stochastic matrices. When the cardinality of a list is 4, Kaddoura and Mourad provided a sufficient condition for SSIEP by a ...

Limit Distributions of Products of Independent and Identically Distributed Random 2 × 2 Stochastic Matrices: A Treatment with the Reciprocal of the Golden Ratio

open access: yesMathematics, 2023
Consider a sequence (Xn)n≥1 of i.i.d. 2×2 stochastic matrices with each Xn distributed as μ. This μ is described as follows.

Optimal Kalman-like filter for a class of nonlinear stochastic systems

open access: yesJournal of Ocean Engineering and Science, 2023
This paper deals with an optimal Kalman-like filter for nonlinear discrete-time systems aided with auto and cross-correlated noises and stochastic parameter matrices involved in state and measurement equations, and random nonlinearity.

On monotone Markov chains and properties of monotone matrix roots

open access: yesSpecial Matrices, 2022
Monotone matrices are stochastic matrices that satisfy the monotonicity conditions as introduced by Daley in 1968. Monotone Markov chains are useful in modeling phenomena in several areas.

Stochastic emulation of quantum algorithms

open access: yesNew Journal of Physics, 2022
Quantum algorithms profit from the interference of quantum states in an exponentially large Hilbert space and the fact that unitary transformations on that Hilbert space can be broken down to universal gates that act only on one or two qubits at the same

An algorithm for constructing integral row stochastic matrices [PDF]

open access: yesJournal of Mahani Mathematical Research, 2022
Let  $\textbf{M}_{n}$ be  the set of all $n$-by-$n$ real  matrices, and let  $\mathbb{R}^{n}$ be  the set of all $n$-by-$1$ real (column) vectors. An $n$-by-$n$ matrix $R=[r_{ij}]$ with nonnegative entries is called row stochastic, if $\sum_{k=1}^{n} r_ ...

On 3-by-3 row stochastic matrices

open access: yesSpecial Matrices, 2023
The known constructive tests for the shapes of the numerical ranges in the 3-by-3 case are further specified when the matrices in question are row stochastic. Auxiliary results on the unitary (ir)reducibility of such matrices are also obtained.

A short note on extreme points of certain polytopes

open access: yesSpecial Matrices, 2020
We give a short proof of Mirsky’s result regarding the extreme points of the convex polytope of doubly substochastic matrices via Birkhoff’s Theorem and the doubly stochastic completion of doubly sub-stochastic matrices.

Representation of the stochastic matrix sets with given properties based on autonomous automatic models

open access: yesУчёные записки Казанского университета: Серия Физико-математические науки, 2019
This paper considers the methods of construction (presentation) of the sets of ergodic stochastic matrices using automaton models and determination of the power estimates of the generated sets. The research aimed at developing algorithms for constructing
