Chapter l Preliminaries 1.1 Introduction Fractional calculus is an important branch of mathematics， which is a generalizationof ordinary differentiation and integration to arbitrary real or complex order. Itis well known that the f'ractional order differential and integral operators are nonlocal operators. This is one reason why fractional differential operators provide anexcellent instrument for description of memory and hereditary properties of variousphysical processes. The subject is as old as differential calculus. In September 30th，1695， G. A. de L'Hospital wrote to G. W. Leibniz asking him about the differentiationof order*G. W. Leibniz response " an apparent paradox from which， one day，useful consequences will be drawn ". After that， many mathematicians made manycontributions iii this field， such as N.H. Abel， A.K. Griinwald， J. Liouville， P.S.Laplace， J.B.J. Fourier， B. Riemann， M. Caputo， etc. However， due to the unclearapplication background， the development of fractional calculus is very slow in theearly stage. It was not uiitil 1970s that B. Mandelbort of Yale proposed fractaltheory and applied RiemannLiouville fractional calculus to study Brownian motionin fractal modia that fractional calculus dcvclopcd rapidly. We observe that fractional order can be complex in viewpoint of pure rnathernaticsand thcrc is much intcrost in dcvoloping the thooretical analysis and numcricalmethods to fractional equations， because they can describe the behavior of realdynamical systems in compact expressions， taking into account nonlocalcharacteristics like infinite memory [22， 23， 138] . Some instance are thermal diffusionphenomenon [39]， botanical electrical impedances [71]， model of love betweenhumans [4]， the relaxation of water on a porous dyke whose damping ratio isindependent of the mass of moving water [134]， and so forth. On the otherhand， dircction the bchavior of a proccss with fractional ordcr controllcrs wouldbe an advantage， because the responses are not restricted to a sum of exponentialfunctions， therefore a wide range of responses neglected by integer order calculuswould be approached [19]. For other advantages of fractional calculus， we can seereal materials [59，131，140，150，177] ， control engineering [3，42] ， electromagnetism [50]，biosciences [110]， fluid mechanics [80]， electrochemistry [132]， anomalous diffusionprocesses [53]， dynamic of viscoelastic materials [83]， viscoelastic systems [13]，continuum and statistical mechanics [112] and propagation of spherical flames[114]， robotic manupulators [139]， gear transmissions [62]， vibration systems [25]，hydrogeology， boundary layer effect of pipeline， signal processing and systemidontification， quantum cconomy， fractal thcory， hcat transfcr， clcctrical circuits，polymer physics， finance， hydrology and even biology [140]， etc. The types of fractional differential equations mainly include neutral differentialequations， f'unctional differential equations， impulsive differential equations，diffcrontial cquations in Banach spacc， partial diffbrontial equation (such as Laplacoequation， diffusion equation， wave equation， Schrodinger equation， NavierStokesequation， Heisenberg equation， Langevin equation， FokkerPlanck equation， etc)，uncertain differential equation (such as stochastic differential equation， fuzzydifferential equation， etc.)， chaotic system， Hamiltonian system， Lorenz system，financial system， neural network， etc. There are several papers regarding abstractforms of fractional partial equations [85， 89]. For more details， we can ref'er to[119， 182184， 188， 189， 193]. This aspcct clcarly indicatcs the importancc andadaptation of fractionalorder operators in the mathematical modeling of scientificand technical problems. For instance， in the study of fractional advectiondispersionequation and fractional FokkerPlanck equation [17， 18]， a laboratory tracer test hasindicated that fractional differential equations approximate Levy motion better thanintegerorder equations. For more details， see [14， 24， 29， 34， 40， 100， 110， 178]. More and more experimental data show that the traditional integerorderdiffusion equations are not enough to describe some anomalous diffusion phenomena.In real life， the regular diffusion phenomenon (integer order case) only occurs in afew special cases. It has been observed that the mean square displacement of adiffusive material is proportional to t when tj in normal diffusion (integerorderdiffusion)， but this proportionality becomos of tho ordcr to for tj oo in casc ofanomalous diffusion. Compared with the traditional diffusion equations (first order)，with fractional diffusion equations， subdifFusion or supdiffusion phenomenon canbe described when its order is between o and I or between I and 2， respectively.For example， if the first derivative is replaced by the fractional order aE (0，1)，the diffusion speed will be slowed down due to the memory characteristics of thefractional derivative， whic
