Piptatherum ferganense (Poaceae), another Middle Asian species as a new record for the flora of Iran
Piptatherum ferganense is recorded as a new grass species for the flora of Iran collected from Ghorkhod Protected Area and Aladagh Mountains in North Khorassan province. The core distribution range of the species is Eastern Irano-Turanian with a disjunction in northeastern Iran. The morphological characters of P. ferganense are illustrated and compared with the closely related P. latifolium. I...
According to a class of constrained minimization problems, the Schwartz symmetrization process and the compactness lemma of Strauss, we prove that there is a nontrivial ground state solution for a class of $p$-Laplace equations without the Ambrosetti-Rabinowitz condition.
Koenig’s infinity lemma states that an infinite rooted tree in which every node has finite degree has an infinite path. A variation of this lemma about mappings from one tree to another is presented in this note. Its proof utilizes Koenig’s lemma, and Koenig’s lemma follows from this variation.
In this work, applying Lemma due to Nunokawa et. al. cite{NCKS}, we obtain some sufficient inequalities for some certain subclasses of univalent functions.
