In the present paper we give a description of the free algebra over an arbitrary set of generators in the variety of nilpotent minimum algebras. Such description is given in terms of a weak Boolean product of directly ...

Total electron content measurements given by the global navigation satellite system (GNSS) have successfully presented results to capture the signatures of equatorial plasma bubbles. In contrast, the correct reproduction ...

Es sabido que durante muchos años en Chile, la enseñanza está basada en una metodología conductista. Esta situación sin duda se ha dado en todas las áreas de la matemática, lo que ha provocado un aprendizaje ...

This work has two independent goals: the first is to classify the minimal varieties of quadratic growth and the second is to get results about the verbally prime Falgebra M2(E), where E is the Grassmann algebra of infinite ...

We re-examine previously found cosmological solutions to eleven-dimensional supergravity in the light of the E10-approach to M-theory. We focus on the solutions with non zero electric field determined by geometric ...

The nonlocal s-fractional minimal surface equation for Σ = ∂E where E is an open set in RN is given by HΣ s (p):= RN χE(x) − χEc(x) dx = 0 for all p ∈ Σ. |x − p|N+s Here 0 < s < 1, χ designates characteristic function, ...

A new tomographic method was developed with the main goal of mapping the ionosphere in the region of Brazil. The ionospheric background was estimated based on ionosonde and radio-occultation measurements to overcome the ...
