Recent advances in domain decomposition methods for large-scale saddle point problems by Nataf, Frédéric, Tournier, Pierre-Henri

“…Scalability of parallel solvers for problems with high heterogeneities relies on adaptive coarse spaces built from generalized eigenvalue problems in the subdomains. The corresponding theory is powerful and flexible but the development of an efficient parallel implementation is challenging. …”

The Cultural Science of Consumption: Brains, Networks, and Identities by Herrmann-Pillath Carsten

“…The paper proposes a general theory of consumer behaviour in ‘social network markets’ – where individual choices are determined by the choices of others – by conceptualising such markets as examples of distributed cognition; itself part of an ‘externalist’ perspective on human identity. …”

A Study of the Impact of Underground Economy on Integral Tax Burden in the Proportional Growth Model under Uncertainty by Akif Musayev, Aygun Musayeva

“…In order to account for imprecision and uncertainty of economic processes, we use the theory of fuzzy sets. A fuzzy integral equation is used to identify an integral tax burden taking into account the contribution of the underground economy for a certain financial (tax) year. …”

About Total Stability of a Class of Nonlinear Dynamic Systems Eventually Subject to Discrete Internal Delays by Manuel De la Sen

“…Some stability extensions are also discussed for the case when the systems are subject to forcing efforts by using links between the controllability and stabilizability concepts from control theory and the existence of stabilizing linear controls. …”

Dark Energy in Spherically Symmetric Universe Coupled with Brans-Dicke Scalar Field by Koijam Manihar Singh, Gauranga C. Samanta

“…The phenomenon of dark energy and its manifestations are studied in a spherically symmetric universe considering the Brans-Dicke scalar tensor theory. In the first model, the dark energy behaves like a phantom type and in such a universe the existence of negative time is validated with an indication that our universe started its evolution before t=0. …”

Relaxing the sharp density stratification and columnar motion assumptions in layered shallow water systems by Adim, Mahieddine, Bianchini, Roberta, Duchêne, Vincent

“…We rigorously justify the bilayer shallow-water system as an approximation to the hydrostatic Euler equations in situations where the flow is density-stratified with close-to-piecewise constant density profiles, and close-to-columnar velocity profiles. Our theory accommodates with continuous stratification, so that admissible deviations from bilayer profiles are not pointwise small. …”
