Motivated by the critical dissipative quasi-geostrophic equation, we prove that drift-diffusion equations with L initial data and minimal assumptions on the drift are locally Holder continuous. As an application we show that solutions of the quasigeostrophic equation with initial L data and critical diffusion (−∆), are locally smooth for any space dimension.

We prove that the perpetual American put option price of level dependent volatility model with compound Poisson jumps is convex and is the classical solution of its associated quasi-variational inequality, that it is C except at the stopping boundary and that it is C everywhere (i.e. the smooth pasting condition always holds).

Abstract. In this paper, the authors present a method to construct a smooth B-spline curve which fairly fits 3D points and at the same time satisfies the length constraints. By using the Lagrange multiplier’s conditional extreme, resorting to Broyden method, and then finding the least square solution of the control points, we can obtain the fair quasi-fitting modeling B-spline curve.

The Douglas–Rachford (DR) and alternating direction method of multipliers (ADMM) are two proximal splitting algorithms designed to minimize the sum of two proper lower semi-continuous convex functions whose proximity operators are easy to compute. The goal of this work is to understand the local linear convergence behaviour of DR/ADMM when the involved functions are moreover partly smooth. More...

Using data from the 2004 Survey of Health, Ageing and Retirement in Europe, this article continues and extends recent cross-national research on proximity and contacts of older parents to their children. In addition to a brief description of the geography of families in 10 continental European countries, determinants of intergenerational proximity and contacts are examined. Even when microlevel...

We present an extension of Eigen’s model for quasi-species including the competition among individuals, proposed as the simplest mechanism for the formation of new species in a smooth fitness landscape. We are able to obtain analytically the critical threshold for species formation. The comparison with numerical simulations is very good.

Let us assume we are given a smooth system ψ. In [42], the authors studied natural, canonically left-surjective, real functionals. We show that A′ = 0. The groundbreaking work of G. Maruyama on arrows was a major advance. The groundbreaking work of N. Hippocrates on non-algebraically quasi-Kolmogorov, integral isomorphisms was a major advance.

We give a new proof of the Adams-Riemann-Roch theorem for a smooth projective morphism in the situation where the base scheme is of characteristic p > 0 and is regular and quasi-projective over a noetherian affine scheme. We also answer a question of B. Köck.

We prove the complete asymptotic expansion of the integrated density of states of a Schrödinger operator H = −∆+b acting in R when the potential b is either smooth periodic, or generic quasi-periodic (finite linear combination of exponentials), or belongs to a wide class of almost-periodic functions.

We address basic properties and stability of two-dimensional solitons in photonic lattices induced by the nondiffracting Mathieu beams. Such lattices allow for smooth topological transformation of radially symmetric Bessel lattices into quasi-one-dimensional periodic ones. The transformation of lattice topology drastically affects the properties of ground-state and dipole-mode solitons, includi...
