Subharmonic Solutions in Singular Systems
The authors consider the problem of bifurcation of periodic solutions in singular systems of differential equations \[ \varepsilon\dot{u}=f(u)+\varepsilon g(t,u,\varepsilon)\quad u\in\mathbb{R}^n, \] where \(g(t+2,u,\varepsilon)=g(t,u,\varepsilon)\) and \(\dot{u}=f(u)\) has an orbit \(\gamma(t)\) homoclinic to a hyperbolic equilibrium point \(p\).

In the theory of ordinary differential equations, the Clairaut equation is well known. This equation is a non-linear differential equation unresolved with respect to the derivative.

The Abrikosov vortex in curved space
We study the self-gravitating Abrikosov vortex in curved space with and with-out a (negative) cosmological constant, considering both singular and non-singular solutions with an eye to hairy black holes.

PERTURBING SINGULAR SOLUTIONS OF THE GELFAND PROBLEM [PDF]
The equation -Δu = λeuposed in the unit ball B ⊆ ℝN, with homogeneous Dirichlet condition u|∂B= 0, has the singular solution [Formula: see text] when λ = 2(N - 2). If N ≥ 4 we show that under small deformations of the ball there is a singular solution (u,λ) close to (U,2(N - 2)).

Investigation the soliton solutions of mussel and algae model leading to concentration
In this study, the abundant families of soliton solutions are constructed for the mussel-algae model which provides information about represents the concentration of algae in the water layer, and mussel biomass of sediment surface in the per square meter.

Exact solutions and singularities in string theory [PDF]
We construct two new classes of exact solutions to string theory which are not of the standard plane wave or gauged WZW type. Many of these solutions have curvature singularities. The first class includes the fundamental string solution, for which the string coupling vanishes near the singularity.

Background. There is no problem in finding a general solution to the ordinary differential Clairaut equation. The corresponding procedure is described in details in the theory of ordinary differential equations.

On singular solutions for second order delayed differential equations
Asymptotic properties and estimate of singular solutions (either defined on a finite interval only or trivial in a neighbouhood of infinity) of the second order delay differential equation with p-Laplacian are investigated.

Singularity of solutions to singular SPDEs
Building on the notes [Hai17], we give a sufficient condition for the marginal distribution of the solution of singular SPDEs on the $d$-dimensional torus to be singular with respect to the law of the Gaussian measure induced by the linearised equation.
