Generalized nonconservative gravitational field equations from Herglotz action principle
Juilson A. P. Paiva, Matheus J. Lazo, Vilson T. Zanchin
We present an alternative nonconservative gravitational theory based on the Herglotz variational principle in a fully covariant form. The present model may be seen as an improvemen…
Calculus of variations and optimal control for generalized functions
Gastao S. F. Frederico, Paolo Giordano, Alexandr A. Bryzgalov +1
We present an extension of some results of higher order calculus of variations and optimal control to generalized functions. The framework is the category of generalized smooth fun…
Why can we observe a plateau even in an out of control epidemic outbreak? A SEIR model with the interaction of distinct populations for Covid-19 in Brazil
Matheus Jatkoske Lazo, Adriano De Cezaro
This manuscript proposes a model of distinct populations interaction structured SEIR to describe the spread of COVID-19 pandemic diseases. The proposed model has the flexibilit…
A deformed derivative model for turbulent diffusion of contaminants in the atmosphere
A. G. Goulart, M. J. Lazo, J. M. S. Suarez
In the present work, we propose an advection-diffusion equation with Hausdorff deformed derivatives to stud the turbulent diffusion of contaminants in the atmosphere. We compare th…
A new parameterization for the concentration flux using the fractional calculus to model the dispersion of contaminants in the Planetary Boundary Layer
A. G. Goulart, M. J. Lazo, J. M. S. Suarez
In the present work, we propose a new parameterization for the concentration flux using fractional derivatives. The fractional order differential equation in the longitudinal and v…
Dark energy with zero pressure: Accelerated expansion and large scale structure in action-dependent Lagrangian theories
Thiago R. P. Caramês, H. Velten, J. C. Fabris +1
We develop a cosmological model based on action-dependent Lagrangian theories. The main feature here is the nonconservation of the energy momentum tensor due to the nontrivial geom…
