On Ext-indices of ring extensions

Saeed Nasseh, Yuji Yoshino

In this paper we are concerned with the finiteness property of Ext-indices of several ring extensions. In this direction, we introduce some conjectures and discuss the relationship…

Quantum cosmology with varying speed of light: canonical approach

P. Pedram, S. Jalalzadeh

We investigate --dimensional cosmology with varying speed of light. After solving corresponding Wheeler-DeWitt equation, we obtain exact solutions in both classical and quan…

Quantum FRW cosmological solutions in the presence of Chaplygin gas and perfect fluid

P. Pedram, S. Jalalzadeh

We present a Friedmann-Robertson-Walker quantum cosmological model in the presence of Chaplygin gas and perfect fluid for early and late time epoches. In this work, we consider per…

Generalized Chaplygin gas as geometrical dark energy

M. Heydari-Fard, H. R. Sepangi

The generalized Chaplygin gas provides an interesting candidate for the present accelerated expansion of the universe. We explore a geometrical explanation for the generalized Chap…

A Heuristic Routing Mechanism Using a New Addressing Scheme

Mohsen Ravanbakhsh, Yasin Abbasi-Yadkori, Maghsoud Abbaspour +1

Current methods of routing are based on network information in the form of routing tables, in which routing protocols determine how to update the tables according to the network ch…
