Continuity of Lyapunov functions and of energy level for generalized gradient semigroup
(JULIUSZ SCHAUDER CTR NONLINEAR STUDIESTORUN, 2012)
The global attractor of a gradient-like semigroup has a Morse decomposition. Associated to this Morse decomposition there is a Lyapunov function (differentiable along solutions)-defined on the whole phase space- which ...
Scaling-up from species to ecosystems: how close can we get to actual decomposition?
(Gauthier-villars/editions Elsevier, 2015-01)
Predicting global changes and their effects on ecosystem functioning has been a central issue of ecology during the last decades. Scaling-up from species characteristics to ecosystem processes is a common approach to ...
Domain Decomposition Methods for Problems in H(curl)
(2015-05)
Two domain decomposition methods for solving vector field problems posed in H(curl) and discretized with Nedelec finite elements are considered. These finite elements are conforming in H(curl). A two-level overlapping ...

On the approximation of a virtual coarse space for domain decomposition methods in two dimensions
(2018)
A new extension operator for a virtual coarse space is presented which can be used in domain decomposition methods for nodal elliptic problems in two dimensions. In particular, a two-level overlapping Schwarz algorithm is ...
Exotic species as modifiers of ecosystem processes: Litter decomposition in native and invaded secondary forests of NW Argentina
(Elsevier Masson, 2014-03)
Invasions of exotic tree species can cause profound changes in community composition and structure, and may even cause legacy effect on nutrient cycling via litter production. In this study, we compared leaf litter ...
Livestock grazing affects microclimate conditions for decomposition process through changes in vegetation structure in mountain grasslands
(Gauthier-Villars/Editions Elsevier, 2018-08)
It is often assumed that a change in litter quality is the main driver of alterations in the decomposition process when grazers modify vegetation structure. Soil microclimate is also modified, but this driver of decomposition ...
A two-level overlapping Schwarz method for H(curl) in two dimensions with irregular subdomains
(2015-10-07)
A bound is obtained for the condition number of a two-level overlapping Schwarz algorithm for problems posed in H(curl) in two dimensions, where the subdomains are only assumed to be John subdomains. The coarse space is ...
