Uniqueness and regularization for unknown spacewise lower-order coefficient and source for the heat type equation
Adriano De Cezaro, Fabiana Travessini De Cezaro
In this contribution we show sufficient conditions for simultaneous unique identification of unknown spacewise coefficients and heat source in a parabolic partial differential equa…
A note on uniqueness in the identification of a spacewise dependent source and diffusion coefficient for the heat equation
Adriano De Cezaro, B. Tomas Johansson
We investigate uniqueness in the inverse problem of reconstructing simultaneously a spacewise conductivity function and a heat source in the parabolic heat equation from the usual…
The DuBois-Reymond Fundamental Lemma of the Fractional Calculus of Variations and an Euler-Lagrange Equation Involving only Derivatives of Caputo
Matheus J. Lazo, Delfim F. M. Torres
Derivatives and integrals of non-integer order were introduced more than three centuries ago, but only recently gained more attention due to their application on nonlocal phenomena…
Supersymmetric reduced minimal 3-3-1 model
D. T. Huong, L. T. Hue, M. C. Rodriguez +1
We build an supersymmetric version of the minimal 3-3-1 model with just two Higgs triplets using the superfield formalism. We study the mass spectrum of all particles in concordanc…
Phase transition of a Heat equation with Robin's boundary conditions and exclusion process
Tertuliano Franco, Patricia Gonçalves, Adriana Neumann
For a heat equation with Robin's boundary conditions which depends on a parameter , we prove that its unique weak solution converges, when goes to zero or to infinit…
Realistic Cyclic Magnetic Universe
L. G. Medeiros
This work presents a complete cyclic cosmological scenario based on nonlinear magnetic field. It is constructed a model composed by five fluids namely baryonic matter, dark matter,…
