Delay-dependent and delay-independent stability of Cournot duopoly model with tax evasion and time-delay
Benjamín A. Itzá-Ortiz, Raúl Villafuerte-Segura, Eduardo Alvarado-Santos
In this paper a stability analysis for a Cournot duopoly model with tax evasion and time-delay in a continuous-time framework is presented. The mathematical model under considerati…
The numerical range of a class of periodic tridiagonal operators
Benjamín A. Itzá-Ortiz, Rubén A. Martínez-Avendaño
In this paper we compute the closure of the numerical range of certain periodic tridiagonal operators. This is achieved by showing that the closure of the numerical range of such o…
Conditions for stable equilibrium in Cournot duopoly models with tax evasion and time delay
Raul Villafuerte-Segura, Eduardo Alvarado-Santos, Benjamin A. Itza-Ortiz
We provide conditions for stable equilibrium in Cournot duopoly models with tax evasion and time delay. We prove that our conditions actually imply asymptotically stable equilibriu…
A class of tridiagonal operators associated to some subshifts
Christian Hernández-Becerra, Benjamín A. Itzá-Ortiz
We consider a class of tridiagonal operators induced by not necessary pseudoergodic biinfinite sequences. Using only elementary techniques we prove that the numerical range of such…
D-Branes in Orientifolds and Orbifolds and Kasparov KK-Theory
H. Garcia-Compean, W. Herrera-Suarez, B. A. Itza-Ortiz +1
A classification of D-branes in Type IIB Op^- orientifolds and orbifolds in terms of Real and equivariant KK-groups is given. We classify D-branes intersecting orientifold planes f…
