New Subclass of Convex Functions Concerning Infinite Cone [PDF]
Sahand Communications in Mathematical AnalysisWe introduce a new subclass of convex functions as follows:\[ \mathcal{K}_{IC}:=\left\{f\in \mathcal{A}:{\rm Re}\left(1+\frac{zf''(z)}{f'(z)}\right)>\left|f'(z)-1\right|,\quad |z|

Early Pliocene Varanus (Squamata, Varanidae) remains from Megalo Emvolon, Thessaloniki, Greece
The Anatomical Record, EarlyView.The article describes new cranial and postcranial varanid material from Megalo Emvolon Lower Pliocene vertebrate fossil site near Thessaloniki. The fossils, likely representing a single individual, are referred to Varanus cf. marathonensis. Abstract This study describes new fossil varanid material from a recently discovered fossil spot (MVL site) at ...

Convexity Properties of the Cone of Nonnegative Polynomials [PDF]
Discrete & Computational Geometry, 2004 We study metric properties of the cone of homogeneous non-negative multivariate polynomials and the cone of sums of powers of linear forms, and the relationship between the two cones. We compute the maximum volume ellipsoid of the natural base of the cone of non-negative polynomials and the minimum volume ellipsoid of the natural base of the cone of ...

The Anatomical Record, EarlyView.Abstract The study of morphological evolution is fundamentally tied to ontogeny, yet studies of these heterochronic processes in the fossil record are rare. Fossils belonging to an ontogenetic series are difficult to assign to an ontogenetic stage due to inconsistent proxies for skeletal ages, challenging to taxonomically assign due to morphological ...

The Second Welfare Theorem with public goods in general economies [PDF]
In this paper we prove a general version of the Second Welfare Theorem for a non-convex and non-transitive economy, with public goods and other externalities in consumption.

The Anatomical Record, EarlyView.Abstract Despite documented ecomorphological shifts toward an herbivorous diet in several coelurosaurian lineages, the evolutionary tempo and mode of these changes remain poorly understood, hampered by sparse cranial materials for early representatives of major clades. This is particularly true for Therizinosauria, with representative crania best known

The intrinsic geometry of a convex surface in Galilean space
Қарағанды университетінің хабаршысы. Математика сериясыThis paper investigates the intrinsic geometry of a convex surface in the Galilean space. The Galilean space, as a special case of a pseudo-Euclidean space, possesses a degenerate metric.

Computing the Radius of Pointedness of a
, 2008 . Let Ξ(H) denote the set of all nonzero closed convex cones in a finite dimensional Hilbert space H. Consider this set equipped with the bounded Pompeiu-Hausdorff metric δ. The collection of all pointed cones forms an open set in the metric space (Ξ(H),

The Anatomical Record, EarlyView.Abstract The upper carbonate concretion levels of the Romualdo Formation (Aptian, Brazil) have yielded several theropod dinosaur remains, including spinosaurids and the coelurosaurs Santanaraptor placidus and Mirischia asymmetrica, the phylogenetic affinities of which are controversial.

Explicit Formula of Koszul–Vinberg Characteristic Functions for a Wide Class of Regular Convex Cones
Entropy, 2016 The Koszul–Vinberg characteristic function plays a fundamental role in the theory of convex cones. We give an explicit description of the function and related integral formulas for a new class of convex cones, including homogeneous cones and cones ...
