تخریب منابع طبیعی و محیط زیست از مهمترین دغدغه ها در مناطق مختلف جهان خصوصا نواحی خشک می باشد. بطوریکه سطوح وسیعی از این اراضی در طیف گسترده ای از فرآیندهای تخریب در حال نابودی می باشد. از این رو ارزیابی و تهیه نقشه آسیب پذیری به زوال پوشش گیاهی در کشورمان می تواند بسیار زیاد ما را در برنامه ریزیهای مدیریتی و اجرایی یاری نماید. درتحقیق حاضرمعیارهای مورد استفاده در یک مدل جدید برای ارزیابی زوال ...

Schwarz showed that when a closed symplectic manifold (M,ω) is symplectically aspherical (i.e. the symplectic form and the first Chern class vanish on π2(M)) then the spectral invariants, which are initially defined on the universal cover of the Hamiltonian group, descend to the Hamiltonian group Ham(M,ω). In this note we describe less stringent conditions on the Chern class and quantum homolog...
