The Fujiki class and positive degree maps

open access: yesComplex Manifolds, 2015
We show that a map between complex-analytic manifolds, at least one ofwhich is in the Fujiki class, is a biholomorphism under a natural condition on the second cohomologies.

Partial Contraction Analysis of Coupled Fractional Order Systems

open access: yesJournal of Applied Mathematics, 2018
Contraction theory regards the convergence between two arbitrary system trajectories. In this article we have introduced partial contraction theory as an extension of contraction theory to analyze coupled identical fractional order systems. It can, also,

Shape maps for second order partial differential equations

open access: yes, 2015
We analyse the singularity formation of congruences of solutions of systems of second order PDEs via the construction of \emph{shape maps}. The trace of such maps represents a congruence volume whose collapse we study through an appropriate evolution ...

Asymptotic solution of the high order partial differential equation

open access: yesVietnam Journal of Mechanics, 2009
In the present paper, the authors have constructed an asymptotic solution of the high order equation with partial derivatives by means of the asymptotic method for the high order systems.

Existence and uniqueness of positive solutions to a fourth-order two-point boundary-value problem

open access: yesElectronic Journal of Differential Equations, 2013
In this article, we study the existence and uniqueness of positive solutions for a class of semi-linear, fourth order two point boundary value problems. Some examples are presented to illustrate our main results.

Holomorphic Gromov’s Partial Order [PDF]

open access: yesThe Journal of Geometric Analysis, 2017
As in [5], we study holomorphic maps of positive degree between compact complex manifolds, and prove that any holomorphic map of degree one from a compact complex manifold to itself is biholomorphic. This conclusion confirms that under a mild restriction the holomorphic Gromov relation ">_" is indeed a partial order.

Nonlocal problem for partial differential equations of fractional order

open access: yesVestnik Samarskogo Gosudarstvennogo Tehničeskogo Universiteta. Seriâ: Fiziko-Matematičeskie Nauki, 2015
A nonlocal problem is investigated for the partial differential equation (diffusion equation of fractional order) in a finite domain. The boundary condition contains a linear combination of generalized operators of fractional integro-differentiation used

On log concavity for order-preserving and order-non-reversing maps of partial orders [PDF]

open access: yes
Stanley used the Aleksandrov-Fenchel inequalities from the theory of nixed volumes to prove the following result. Let P be a partially ordered set with n elements, and let x ∊ P.
