NP-hardness of deciding convexity of quartic polynomials and related problems [PDF]
, 2010 We show that unless P = NP, there exists no polynomial time (or even pseudo-polynomial time) algorithm that can decide whether a multivariate polynomial of degree four (or higher even degree) is globally convex.

Some Classes of Pseudoconvex Fractional Functions via the Charnes and Cooper Transformation
, 2007 Using a very recent approach based on the Charnes-Cooper trasformation we characterize the pseudoconvexity of the sum between a quadratic fractional function and a linear one. Furthemore we prove that the ratio between a quadratic fractional function and

Pseudoconvexity and the envelope of holomorphy for functions of several complex variables
, 1966 We first handle some generalizations from the theory of functions of a single complex variable, including results regarding analytic continuation. Several "theorems of continuity" are considered, along with the associated definitions of pseudoconvexity,

Geometry of Semi-tube Domains in ℂ2
, 2012 In this paper we study a class of unbounded domains in ℂ2 which are invariant with respect to translations in some fixed real direction. Such domains will be called semi-tubes.

On generalized convexity of quadratic fractional functions
, 2002 In this paper the generalized convexity of quadratic fractional functions is studied. It is proved that, for this class of functions, pseudoconvexity is equivalent to quasiconvexity and some characterizations for both pseudoconvexity and strict ...

Characterizing the generalized convexity of a quadratic fractional function
, 2019 The aim of this paper is to investigate the generalized convexity of a quadratic fractional function. New characterizations are provided for both pseudoconvexity and strict pseudoconvexity.

Generalized convex set functions
, 1989 Concepts of quasiconvexity and pseudoconvexity of set functions are introduced. Properties and relations between these generalized convex set functions are investigated, and optimality criteria for differentiable and convex set functions are extended to ...

Regularity at the boundary for $barpartial$ on q-pseudoconvex domains
, 2005 Solvability for /9 with regularity at the boundary of a domain f/CC C n for forms of any degree k > 1 was characterized by pseudoconvexity of 0[2 in [ 16]. It is proved here that q-pseudoconvexity suffices to guarantee solvability of forms of degree k _>
