We classify quasi-simple finite groups of essential dimension 3.

In this paper, we characterize ordered semigroups in terms of fuzzy quasi-ideals. We characterize left simple, right simple and completely regular ordered semigroups in terms of fuzzy quasi-ideals. We define semiprime fuzzy quasi-ideal of ordered semigroups and characterize completely regular ordered semigroup in terms of semiprime fuzzy quasi-ideals. We also study the decomposition of left and...

It has been known for a long time that many simple liquids have surprisingly similar structure as quantified, for example, by the radial distribution function. A much more recent realization is that the dynamics are also very similar for a number of systems with quite different pair potentials. Systems with such non-trivial similarities are generally referred to as 'quasi-universal'. From the f...

We show that real rational (over C) surfaces are quasi-simple, i.e., that such a surface is determined up to deformation in the class of real surfaces by the topological type of its real structure.

This paper provides a novel axiomatization of quasi-hyperbolic discounting, which imposes consistency restrictions directly on the intertemporal tradeoffs. The experimental design proposed in this paper will be useful for experimental work since it renders the short-run discount factor elicitation independent of the utility function. This makes comparisons of impatience across a spectrum of dif...
