We consider a relativistic particle under the action of a time-periodic central force field in the plane. Assuming an attractive type condition on some neighborhood of infinity there are many subharmonic and quasiperiodic motions. Moreover, the obtained information allows to give applications for many scalar problems involving the relativistic operator. MSC 2010 Classification : 34C25, 34B16, 7...

A higher order corrector-predictor interior-point method is proposed for solving sufficient linear complementarity problems. The algorithm produces a sequence of iterates in the N− ∞ neighborhood of the central path. The algorithm does not depend on the handicap κ of the problem. It has O((1 + κ) √ nL) iteration complexity and is superlinearly convergent even for degenerate problems.

An interior point method for monotone linear complementarity problems acting in a wide neighborhood of the central path is presented. The method has O( √ nL)iteration complexity and is superlinearly convergent even when the problem does not possess a strictly complementary solution.

In the site of Gird-i Bazar in Sulaymaniyah province, a Sasanian cemetery was found installed over, and partly damaging, older Iron Age structures. Although Zoroastrians notoriously exposed bodies then placed bones into astodans, inhumations are not uncommon such multi-cultural empire. After mentioning cemeteries same region underlining presence large Christian community Adiabene, author descri...
