We consider the system of equations of viscous gas motion whose pressure is related to the density by the law
$p = h \varrho^\gamma$
with 1<γ <2, in a domain defined by two levels of geopotential. Under the force due to geopotential and the Coriolis force, we prove the stability of the...
We study the system of equations describing a stationary thermoconvective flow of a non-Newtonian fluid. We assume that the stress tensor S has the form
Here we address a Waring type problem for partially symmetric tensors, extending previous work by Massimiliano Mella in the totally symmetric case of forms. In particular, we provide an explicit answer in lower dimensional cases.
The main results of this paper give two criteria for certain infinite series of rational numbers to be Liouville. Some examples are also included.
This paper deals with the existence of weak periodic solutions for a parabolic-elliptic system proposed as a model for a time dependent thermistor with degenerate thermal conductivity. Applying the maximal monotone mappings theory, we prove an existence result for weak periodic solutions.
In this paper we consider the problem of global analytic and Gevrey hypoellipticity and solvability for a class of partial differential operators on a torus. We prove that global analytic and Gevrey hypoellipticity and solvability on the torus is equivalent to certain Diophantine approximation...
We present a uniqueness result for the Cauchy problem associated to a particular type of ordinary differential equation (ODE), under the only assumption of continuity of the right hand side at the initial point.
This note shows that in the hyperbolic plane three kinds of coordinates are possible.
The authors characterize the finite groups in which
, the intersection of the maximal non-nilpotent subgroups of G, is nilpotent, but different from Φ(G). Further, if
is a saturated formation and if
is the intersection of all...
We give a generalization of the identity proved by J. Worpitzky in , by expressing each power x
as a linear combination of the images of β
under the powers of the shift operator E (here
). We encode the coefficients of these linear...
