karaki, an outstanding faqih in 10th century (ah), was the first to cooperate with the safavids, hence founding the basis for the convergence of the ulama and the state in the safavid era. his theoretical contribution lies on the proposal of the theory of the sovereignty of faqih. with karaki being scientifically and politically famous, his theory soon became wide-spread in this period and was ...

We study a variational problem arising in the approach of Mumford and Shah to the image segmentation problem of computer vision Given f L D for a domain D in R the simpli ed Mumford Shah energy associated to a decompositionD N is

The aim of this paper is to prove the existence of extension operators for SBV functions from periodically perforated domains. This result will be the fundamental tool to prove the compactness in a non coercive homogenization problem.

baladieh as a new administration, has started its operation from the constitutional era, and in reza shah's reign continued its undertakings more seriously in the field of urban planning, cleaning, and supply needs of the citizens. part of the baladieh actions was in the field of public health. documents clearly indicate the baladieh's attempt to reorganize community's health sta...

We present a general theory to study optimal regularity for a large class of nonlinear elliptic systems satisfying general boundary conditions and in the presence of a geometric transmission condition on the free-boundary. As an application we give a full positive answer to a conjecture of De Giorgi on the analyticity of local minimizers of the Mumford-Shah functional.
