Boundary value problems for strongly nonlinear equations under a Wintner-Nagumo growth condition [PDF]
We study the following strongly nonlinear differential equation: ( a ( t , x ( t ) ) Φ ( x ′ ( t ) ) ) ′ = f ( t , x ( t ) , x ′ ( t ) ) , a.e. in [ 0 , T ] $$\bigl(a \bigl(t,x(t) \bigr)\Phi\bigl(x'(t) \bigr) \bigr)'= f \bigl(t,x(t),x'(t) \bigr), \quad ...

In this paper, we consider the following $(n+1)$st order bvp on the half line with a $\phi-$Laplacian operator $$ \begin{cases} (\phi(u^{(n)}))'(t)=f(t,u(t),\ldots,u^{(n)}(t)),& a.e., \,t\in [ 0,+\infty ),\\& n\in \mathbb{N}\setminus\{0\}, \\ u^

We study the synchronization behavior of a class of identical FitzHugh-Nagumo-type oscillators under adaptive coupling. We describe the oscillators by a circuit model and we provide a sufficient synchronization condition that relies on the shape of the ...

A third order boundary value problem with one-sided Nagumo condition
In this paper we present an existence and location result for the third order separated boundary value problem composed by the differential equation u′′′(t)=f(t,u(t),u′(t),u′′(t)) with the boundary conditons u(a)=A, u′′(a)=0 and u′′(b)=0, where f:[a,b]×

Semigroups generated by pseudo-contractive mappings under the Nagumo condition
Let X be a Banach space whose dual space X∗ is uniformly convex. We demonstrate that, for any demicontinuous, weakly Nagumo, k-pseudo-contractive mapping T:D(T)⊆X→X with closed domain, A=T−I weakly generates a semigroup on D(T). In this paper, we project

Positive Invariance Condition for Continuous Dynamical Systems Based on Nagumo Theorem
In this paper, we obtain sufficient and necessary conditions of some classical convex sets as positively invariant sets for a continuous dynamical system, namely positive invariance conditions.
