On the monotonic properties and oscillatory behavior of solutions of neutral differential equations
Demonstratio Mathematica, 2023 In this work, we study new asymptotic properties of positive solutions of the even-order neutral differential equation with the noncanonical operator. The new properties are iterative, which means they can be used several times.

Even-Order Neutral Delay Differential Equations with Noncanonical Operator: New Oscillation Criteria
Fractal and Fractional, 2022 The main objective of our paper is to investigate the oscillatory properties of solutions of differential equations of neutral type and in the noncanonical case. We follow an approach that simplifies and extends the related previous results.

Oscillation criteria for even order neutral difference equations [PDF]
Opuscula Mathematica, 2019 In this paper, we present some new sufficient conditions for oscillation of even order nonlinear neutral difference equation of the form \[\Delta^m(x_n+ax_{n-\tau_1}+bx_{n+\tau_2})+p_nx_{n-\sigma_1}^{\alpha}+q_nx_{n+\sigma_2}^{\beta}=0,\quad n\geq n_0 ...

Neutral differential equations with noncanonical operator: Oscillation behavior of solutions
AIMS Mathematics, 2021 The objective of this work is to study the oscillatory behavior of neutral differential equations with several delays. By using both Riccati substitution technique and comparison with delay equations of first-order, we establish new oscillation criteria.

Oscillation Criteria for Qusilinear Even-Order Differential Equations
Mathematics, 2023 In this study, we extended and improved the oscillation criteria previously established for second-order differential equations to even-order differential equations. Some examples are given to demonstrate the significance of the results accomplished.

Totally Critical Even Order Graphs
Journal of Combinatorial Theory, Series B, 1999 A connected graph \(G\) is totally critical if its total chromatic number is at least two more than its maximum degree and is reduced by the removal of an arbitrary edge. Let \(G(p,q)\) have maximum degree \(\Delta(G)\); the deficiency of \(G\) is given by \(\text{def}(G)= \Delta(G)p- 2q\).

Positive Definiteness and Semi-Definiteness of Even Order Symmetric Cauchy Tensors [PDF]
, 2014 Motivated by symmetric Cauchy matrices, we define symmetric Cauchy tensors and their generating vectors in this paper. Hilbert tensors are symmetric Cauchy tensors.

Journal of Algebra, 1994 \textit{O. Chein} [Trans. Am. Math. Soc. 188, No. 2, 31-51 (1974; Zbl 0263.20007)] and \textit{M. Purtill} [J. Algebra 112, 122-128 (1988; Zbl 0644.20040)] investigated Moufang loops \(L\) of even order \(n\) and proved that \(L\) are groups if \(n = 2^ k\) \((0 \leq k \leq 4)\) or \(n = 2p\) (\(p\) is any prime) or \(n = 2p^ 2\).
