Nonlinear Analysis and Its Applications in Symmetry

Nonlinear approximation and its applications

I first met Wolfgang Dahmen in 1974 in Oberwolfach. He looked like a high school student to me but he impressed everyone with his talk on whether polynomial operators could produce both polynomial and spectral orders of approximation. We became the best of friends and frequent collaborators. While Wolfgang’s mathematical contributions spread across many disciplines, a major thread in his work h...

the west of esfahan province, iran, is one of the most important agricultural areas throughout the country due to the climate variability and life-giving water of zayanderood river. rice is one of the major and economic crops in this area. the most important climatic elements in agricultural activities which should be considered include temperature, relative humidity, precipitation and wind. so...

COSY INFINITY and Its Applications in Nonlinear

The Fortran-based environment COSY INFINTIY, as well as the related codes DAFOR and DAPRE, is presented. The codes contain modules for the computation of derivatives to very high orders in many variables, with a particular emphasis on sparsity. The main use of the code lies in the field of nonlinear dynamics, where it is used for the computation of perturbation expansions of Poincare maps to hi...

Cryotherapy and its applications in dermatology

Cryotherapy is a simple, safe and effective method for many benign and malignant skin diseases. If applied with an appropriate technique, the results will be very satisfactory and the complications will be very low. Herewith we will discuss cryotherapy and its applications in dermatology and review the advantages and disadvantages of this technique.
