Fermat type differential and difference equations
Electronic Journal of Differential Equations, 2015 This article we explore the relationship between the number of differential and difference operators with the existence of meromorphic solutions of Fermat type differential and difference equations. Some Fermat differential and difference equations of

Entire solutions for a delayed lattice competitive system
Advances in Difference Equations, 2019 In this paper, we investigate the existence of entire solutions for a delayed lattice competitive system. Here the entire solutions are the solutions that exist for all (n,t)∈Z×R $(n,t)\in \mathbb{Z}\times \mathbb{R}$. In order to prove the existence, we

Existence of entire solutions for semilinear elliptic systems under the Keller-Osserman condition
Electronic Journal of Differential Equations, 2011 Under the Keller-Osserman condition on $f+g$, we show the existence and nonexistence of entire solutions for the semilinear elliptic system $Delta u =p(x)f(v), quad Delta v =q(x)g(u),quad xin mathbb{R}^N$, where $p,q:mathbb{R}^No [0,infty)$ are ...

Existence for (p, q) critical systems in the Heisenberg group
Advances in Nonlinear Analysis, 2019 This paper deals with the existence of entire nontrivial solutions for critical quasilinear systems (𝓢) in the Heisenberg group ℍn, driven by general (p, q) elliptic operators of Marcellini types.

Entire solutions to semilinear nonlocal equations in $\RR^2$
, 2015 We consider entire solutions to $L u= f(u)$ in $\RR^2$, where $L$ is a general nonlocal operator with kernel $K(y)$. Under certain natural assumtions on the operator $L$, we show that any stable solution is a 1D solution.

Entire solutions of the abstract cauchy problem
Semigroup Forum, 1991 In the past several generalizations of strongly continuous one parameter semigroups and their infinitesimal generators were introduced in connection with Cauchy-problems, e.g. polynomials of generators, integrated semigroups, operator matrices and \(C\)- semigroups.

Prevalence and Trajectory of Household Material Hardship Among Children With Advanced Cancer
Pediatric Blood &Cancer, EarlyView.ABSTRACT Background/Objectives Families of children with advanced cancer living in poverty experience inferior outcomes including poor parent mental health and worse child quality of life. Household material hardship (HMH: food, housing, transportation, and/or utility insecurity) is a modifiable poverty exposure—and potential intervention target—that ...
