Novel priori-knowledge-free manoeuvring target-tracking method
The Journal of Engineering, 2019 In the past few decades, many manoeuvring target-tracking methods have been proposed. However, most of these methods require some priori knowledge about the target, which is hard to obtain in many scenarios.

Polynomial reconstruction of the matching polynomial
Electronic Journal of Graph Theory and Applications, 2015 The matching polynomial of a graph is the generating function of the numbers of its matchings with respect to their cardinality. A graph polynomial is polynomial reconstructible, if its value for a graph can be determined from its values for the vertex-deleted subgraphs of the same graph.

SIAM Journal on Optimization, 2019 In this paper, we study polynomial norms, i.e. norms that are the $d^{\text{th}}$ root of a degree-$d$ homogeneous polynomial $f$. We first show that a necessary and sufficient condition for $f^{1/d}$ to be a norm is for $f$ to be strictly convex, or equivalently, convex and positive definite.

Proceedings of the 50th Annual ACM SIGACT Symposium on Theory of Computing, 2018 The approximate degree of a Boolean function $f(x_{1},x_{2},\ldots,x_{n})$ is the minimum degree of a real polynomial that approximates $f$ pointwise within $1/3$. Upper bounds on approximate degree have a variety of applications in learning theory, differential privacy, and algorithm design in general.

Ratio Mathematica, 2023 This paper presents a new approach of using polynomials such as Hermite, Bernoulli, Chebyshev, Fibonacci and Bessel to solve neutral delay differential equations. The proposed method is based on the truncated polynomial expansion of the function together

Multivariate Jacobi and Laguerre polynomials, infinite-dimensional extensions, and their probabilistic connections with multivariate Hahn and Meixner polynomials [PDF]
, 2008 Multivariate versions of classical orthogonal polynomials such as Jacobi, Hahn, Laguerre, Meixner are reviewed and their connection explored by adopting a probabilistic approach.

On Entire and Analytic Functions of the Matrices AB and BA [PDF]
Mathematics Interdisciplinary ResearchThe relation $z^{q}\chi_{AB}(z)=z^{p}\chi_{BA}(z)$ holds for the characteristic polynomials of complex matrices $A_{p\times q}$ and $B_{q\times p}$. In the present paper, we generalize this relation for "complex polynomials", "entire functions,"
