—In this paper, we classify multitolerant systems, i.e., systems that tolerate multiple classes of faults and provide potentially different levels of tolerance to them in terms o...
Starting from a decomposition result of MTL-chains as ordinal sums, we focus our attention on a particular kind of indecomposable semihoops, namely weakly cancellative semihoops. ...
We present a classification that groups lookback into four types: direct strong lookback, universal strong lookback, direct weak lookback, and universal weak lookback. They are d...
In this paper we explore the minimal system requirements to implement unreliable failure detectors. We first consider systems formed by lossy asynchronous and eventually timely l...
Identifying intrinsic structures in large networks is a fundamental problem in many fields, such as engineering, social science and biology. In this paper, we are concerned with c...
