A Generalization of the Fujisawa–Kuh Global Inversion Theorem
We discuss the problem of global invertibility of nonlinear maps defined on the finite dimensional Euclidean space via differential tests. We provide a generalization of the Fujisawa-Kuh global inversion theorem and introduce a generalized ratio condition which detects when the pre-image of a certain class of linear manifolds is non-empty and connected. In particular, we provide conditions that...

متن کاملBiostratigraphy correlation, of Cretaceous successions in Kuh-e-Rahmat and Kuh-e-Sabz sections, NE Shiraz, Zagros (SW Iran)
Two stratigraphic sections (Kuh-e-Rahmat and Kuh-e-Sabz) of Upper Cretaceous strata in the Interior Fars region (SW of Iran) were selected. Lower Cretaceous succession of Kuh-e-Rahmat was consisted of Dariyan, Kazhdumi Sarvak and Ilam Formations.

متن کاملMicrobiostratigraphy of the Oligo-Miocene Asmari Formation, Kuh Siah Anticline (Izeh Basin), SW Iran
This research focusses on the biostratigraphy and paleoecological implications of the carbonatesof the Asmari Formation. The Asmari Formation is located in the Siah Kuhanticline of Izeh, Zagros Basin, SW Iran. It is of Late Oligocene (Chattian) - Early Miocene (Burdigalian) age. In this stratigraphic section, the Asmari Formation overlies the Pabdeh Formation and underlies the Gachsaran Formati...
متن کاملFloristic characteristics of the Hyrcanian submountain forests (case study: Ata-Kuh forest)
Ata-Kuh forest, a preserved area within Hyrcanian relict forests, with an area of 700 ha is located in north of Iran. Based on floristic studies from 2011 through 2012, 194 vascular plant species were identified belonging to 143 genera and 66 families. Among our samples, 24 taxa were endemic to Hyrcanian area. The largest families in the area were Rosaceae (10.3 %), Poaceae (9.7 %), Asteraceae ...
