Engineering lattice models with tailored inter-site tunnelings and onsite energies could synthesize essentially arbitrary Riemannian surfaces with highly tunable local curvatures. Here, we point out that discrete synthetic Poincare half-planes and Po

The Nelder-Mead simplex method is a widespread applied numerical optimization method with a vast number of practical applications, but very few mathematically proven convergence properties. The original formulation of the algorithm is stated in Rn us

[EN] Historically, the Poincare disk model has taken a pioneering role in the development of non-Euclidean geometry. But still today, this model is critical as a playground for simulations and new theories. In this paper, we discuss how to implement

We consider the traveling wave solutions of the degenerate nonlinear parabolic equation $$u_{t}=u^{p}(u_{xx}+u)$$ which arises in the model of heat combustion, solar flares in astrophysics, plane curve evolution problems and the resistive diffusion o

In this paper, we shall study the parabolic-elliptic Keller--Segel system on the Poincare disk model of the two-dimensional-hyperbolic space. We shall investigate how the negative curvature of this...

We completely characterize the global phase portraits in the Poincare disk for all planar Hamiltonian vector fields with linear plus cubic homogeneous terms having a nilpotent saddle at the origin.

We provide canonical forms for the homogeneous polynomials of degree five. Then we characterize all the phase portraits in the Poincare disk for all quartic homogeneous polynomial differential systems. More precisely, there are exactly 23 different t
