Metric Temporal Logic with Counting

Khushraj Madnani, Shankara Narayanan Krishna, Paritosh Pandya

Ability to count number of occurrences of events within a specified time interval is very useful in specification of resource bounded real time computation. In this paper, we study…

Fundamental Group of some Genus-2 Fibrations and Applications

R. V. Gurjar, Sagar Kolte

We will prove that given a genus-2 fibration $f : X \to C$ on a smooth projective surface $X$ such that $b_{1} (X) = b_{1} (C) + 2$ , the fundamental group of $X$ is almost isomorphic…

Thermal effect on mixed state geometric phases for neutrino propagation in a magnetic field

Da-Bao Yang, Ji-Xuan Hou, Ku Meng

In astrophysical environments, neutrinos may propagate over a long distance in a magnetic field. In the presence of a rotating magentic field, the neutrino spin can flip from left-…

Abstraction-driven Concolic Testing

Przemysław Daca, Ashutosh Gupta, Thomas A. Henzinger

Concolic testing is a promising method for generating test suites for large programs. However, it suffers from the path-explosion problem and often fails to find tests that cover d…
