Six-Dimensional Jordan Supergravity Models

P. Kouroumalou

In the context of six-dimensional supergravity there is a special class of parent models for five-dimensional theories defined by the four Euclidean simple Jordan algebras of degre…

Customer Equilibrium and Optimal Strategies in an M/M/1 Queue with Dynamic Service Control

Y. Dimitrakopoulos, A. Burnetas

We consider the problem of customer equilibrium strategies in an M/M/1 queue under dynamic service control. The service rate switches between a low and a high value depending on sy…

Speed scaling with power down scheduling for agreeable deadlines

Evripidis Bampis, Christoph Dürr, Fadi Kacem +1

We consider the problem of scheduling on a single processor a given set of n jobs. Each job j has a workload w_j and a release time r_j. The processor can vary its speed and hibern…

On the Practicality of `Practical' Byzantine Fault Tolerance

Nikos Chondros, Konstantinos Kokordelis, Mema Roussopoulos

Byzantine Fault Tolerant (BFT) systems are considered by the systems research community to be state of the art with regards to providing reliability in distributed systems. BFT sys…

Dilation theory, commutant lifting and semicrossed products

Kenneth R. Davidson, Elias G. Katsoulis

We take a new look at dilation theory for nonself-adjoint operator algebras. Among the extremal (co)extensions of a representation, there is a special property of being fully extre…

Stochastic Burgers PDEs with random coefficients and a generalization of the Cole-Hopf transformation

Nikolaos Englezos, Nikolaos Frangos, Xanthi-Isidora Kartala +1

This paper studies forward and backward versions of random Burgers equation (RBE) with stochastic coefficients. Firstly, the celebrated Cole-Hopf transformation reduces the forward…

Diffusion in Social Networks with Competing Products

Krzysztof R. Apt, Evangelos Markakis

We introduce a new threshold model of social networks, in which the nodes influenced by their neighbours can adopt one out of several alternatives. We characterize the graphs for w…

An improved method for the computation of the Moore-Penrose inverse matrix

Vasilios N. Katsikis, Dimitrios Pappas, Athanassios Petralias

In this article we provide a fast computational method in order to calculate the Moore-Penrose inverse of singular square matrices and of rectangular matrices. The proposed method…

Intersection Logic in sequent calculus style

Simona Ronchi Della Rocca, Alexis Saurin, Yiorgos Stavrinos +1

The intersection type assignment system has been designed directly as deductive system for assigning formulae of the implicative and conjunctive fragment of the intuitionistic logi…
