On different $q$-systems in nonextensive thermostatistics

, 2005
It is known that the nonextensive statistics was originally formulated for the systems composed of subsystems having same $q$. In this paper, the existence of composite system with different $q$ subsystems is investigated by fitting the power law degree ...

Extended Representations of Observables and States for a Noncontextual Reinterpretation of QM [PDF]

, 2011
A crucial and problematical feature of quantum mechanics (QM) is nonobjectivity of properties. The ESR model restores objectivity reinterpreting quantum probabilities as conditional on detection and embodying the mathematical formalism of QM into a ...

The kinked demand curve and price rigidity: evidence from scanner data [PDF]

, 2006
This paper uses scanner data from a large euro area retailer. We extend Deaton and Muellbauer's Almost Ideal Demand System to estimate the price elasticity and curvature of demand for a wide range of products.

Heat equation and convolution inequalities

, 2013
It is known that many classical inequalities linked to convolutions can be obtained by looking at the monotonicity in time of convolutions of powers of solutions to the heat equation, provided that both the exponents and the coefficients of diffusions ...
