Abstract

In this paper, we study the geometrothermodynamics of(2 + 1)-dimensional spinning dilaton black hole. We show that the Ruppeiner curvature vanishes, which implies that there exist no phase transitions and thermodynamic interactions. However when the thermodynamics fluctuation is included, the geometry structure is reconsidered. The non-vanishing Ruppeiner curvature is obtained, which means the phase space is non-flat. We also study the phase transitions and show that it can indeed take place at some points.

Abstract

In this paper, starting with the well known U(1) Chern–Simons Lagrangian and the covariant derivative of a complex scalar matter field, we give a detailed discussion of some topological properties of anyons. We show that the 'basic' charge carried by anyons has an inner structure and can be decomposed in terms of the Chern–Simons coupling and the gauge coupling constants of the theory. Also some incorrect results obtained in the literature are revised.

24. No-chattering sliding mode control in a class of fractional-order chaotic systems

Abstract

A no-chattering sliding mode control strategy for a class of fractional-order chaotic systems is proposed in this paper. First, the sliding mode control law is derived to stabilize the states of the commensurate fractional-order chaotic system and the non-commensurate fractional-order chaotic system, respectively. The designed control scheme guarantees the asymptotical stability of an uncertain fractional-order chaotic system. Simulation results are given for several fractional-order chaotic examples to illustrate the effectiveness of the proposed scheme.
