Concentration solutions to the singularly prescribed Gaussian and geodesic curvatures problem [PDF]
We consider the following Liouville-type equation with exponential Neumann boundary condition: $$ - \tilde u = \varepsilon^2 K(x) e^{2\tilde u}, \quad x\in D, \qquad \frac{\partial \tilde u}{\partial n} + 1 = \varepsilon (x) e^{\tilde u}, \quad x\in\partial D, $$ where $D\subset \mathbb R^2$ is the unit disc, $\varepsilon^2 K(x)$ and $\varepsilon (

A problem of prescribing Gaussian curvature on $S^2$ [PDF]
Summary: A class of functions \(K(x)=K(x_1,x_2,x_3)\) and the corresponding solutions of \[ \Delta u + K(x)e^{2u}=1, \quad x\in S^2, \] are obtained as a special case of the solutions of \[ \Delta^mu+K(x)e^{au}=f(x),\qquad x=(x_1,x_2,\dots,x_n)\in \mathbb{R}^n, \] where \(\Delta^m\) is defined as \(\Delta(\Delta^{m-1})\).

A Note on the Problem of Prescribing Gaussian Curvature on Surfaces [PDF]
The paper treats the problem of prescribing the Gaussian curvature on a surface of genus at least two. Let \((M,g)\) be a closed connected 2- dimensional Riemannian manifold with Gaussian curvature \(k\). If \(g' = e^{2n} \cdot g\) is a conformally equivalent metric, then its curvature is given by \(k' = e^{-2n}\) \((k - \Delta n)\).

A flow approach to the prescribed Gaussian curvature problem in $\mathbb{H}^{n+1}$
In this paper, we study the following prescribed Gaussian curvature problem $$K=\frac{\tilde{f}(θ)}{ϕ(ρ)^{α-2}\sqrt{ϕ(ρ)^2+|\bar{\nabla}ρ|^2}},$$ a generalization of the Alexandrov problem ($α=n+1$) in hyperbolic space, where $\tilde{f}$ is a smooth positive function on $\mathbb{S}^{n}$, $ρ$ is the radial function of the hypersurface, $ϕ(ρ)=\sinhρ$ and

Existence and non existence results for the singular Nirenberg problem [PDF]
In this paper we study the problem, posed by Troyanov (Trans AMS 324: 793–821, 1991), of prescribing the Gaussian curvature under a conformal change of the metric on surfaces with conical singularities.

Minimal resonances in annular non-Euclidean strips [PDF]
Differential growth processes play a prominent role in shaping leaves and biological tissues. Using both analytical and numerical calculations, we consider the shapes of closed, elastic strips which have been subjected to an inhomogeneous pattern of ...

Compactness issues and bubbling phenomena for the prescribed Gaussian curvature equation on the Torus [PDF]
In the spirit of the paper "Large conformal metrics of prescribed Gauss curvature on surfaces of higher genus" by Borer-Galimberti-Struwe, where we dealt with the case of a closed Riemann surface $(M,g_0)$ of genus greater than one, here we study the ...
