We prove that the discrete logarithm problem can be solved in quasi-polynomial expected time multiplicative group of finite fields fixed characteristic. More generally, we it field cardinality p n ...

Abstract The spread of an infectious disease is well approximated by metapopulation networks connected human mobility flow and upon which epidemiological model defined. In order to account for travel restrictions or cancellation we introduce a with parameter that explicitly indicates the ratio between time scales intervening processes. We study critical properties epidemic process its dependenc...
