Asymptotically Diagonal Delay Differential Systems

open access: yesJournal of Mathematical Analysis and Applications, 1996
The paper deals with the equation \[ x'(t)=(\tilde A+A(t))x(t)+(\tilde B+B(t))x(t-\tau), \] where \(\tau\) is a positive constant. Here \smallskip \((H_1)\) \(\tilde A,\tilde B\) are constant diagonal matrices \(\tilde A=\text{ diag }\big\{ \tilde a_1,\tilde a_2,\ldots,\tilde a_n\big\},\) \(\tilde B=\text{ diag }\big\{ \tilde b_1,\tilde b_2,\ldots ...

Approximate solutions of stochastic differential delay equations with Markovian switching [PDF]

open access: yes, 2010
Our main aim is to develop the existence theory for the solutions to stochastic differential delay equations with Markovian switching (SDDEwMSs) and to establish the convergence theory for the Euler-Maruyama approximate solutions under the local ...

Numerical Computation of Takens-Bogdanov Points for Delay Differential Equations

open access: yes, 2012
The paper presents a numerical technique for computing directly the Takens-Bogdanov points in the nonlinear system of differential equations with one constant delay and two parameters. By representing the delay differential equations as abstract ordinary

Clinical Insights Into Hypercalcemia of Malignancy in Childhood

open access: yesPediatric Blood &Cancer, EarlyView.
ABSTRACT Hypercalcemia of malignancy (HCM) is a rare but life‐threatening metabolic emergency in children that occurs in less than 1% of pediatric cancer cases, with a reported incidence ranging from 0.4% to 1.0% across different studies. While it is observed in 10%–20% of adult malignancies, pediatric HCM remains relatively uncommon.

On the Fundamental Analyses of Solutions to Nonlinear Integro-Differential Equations of the Second Order

open access: yesMathematics, 2022
In this article, a scalar nonlinear integro-differential equation of second order and a non-linear system of integro-differential equations with infinite delays are considered.

On positive solutions and the Omega limit set for a class of delay differential equations

open access: yes, 2012
This paper studies the positive solutions of a class of delay differential equations with two delays. These equations originate from the modeling of hematopoietic cell populations. We give a sufficient condition on the initial function for $t\leq 0$ such
