5 4 Giving up the hypothesis of differentiability of space-time Explicit dependence of coordinates in terms of scale variables + divergence --> (theory :  = dX ; experiment :  = apparatus resolution) Generalize relativity of motion ? Transformations of non- differentiable coordinates ? …. Theorem FRACTAL SPACE-TIME Complete laws of physics by fundamental scale laws Continuity + SCALE RELATIVITY

6 5 Principle of scale relativity Scale covariance Generalized principle of equivalence Linear scale-laws: “Galilean” self-similarity, constant fractal dimension, scale invariance Linear scale-laws : “Lorentzian” varying fractal dimension, scale covariance, invariant limiting scales Non-linear scale-laws: general scale-relativity, scale dynamics, gauge fields Constrain the new scale laws…

7 6 1. Continuity + nondifferentiabilityScale dependence Continuity + Non-differentiability implies Fractality when

8 7 Continuity + Non-differentiability implies Fractality

9 8 divergence Lebesgue theorem (1903): « a curve of finite length is almost everywhere differentiable » Since F is continuous and no where or almost no where differentiable i.e., F is a fractal curve 2. Continuity + nondifferentiability when

10 9 *Re-definition of space-time resolution intervals as characterizing the state of scale of the coordinate system *Relative character of the « resolutions » (scale-variables):only scale ratios do have a physical meaning, never an absolute scale *Principle of scale relativity: « the fundamental laws of nature are valid in any coordinate system, whatever its state of scale » *Principle of scale covariance: the equations of physics keep their form (the simplest possible)* in the scale transformations of the coordinate system Weak : same form under generalized transformations Strong : Galilean form (vacuum, inertial motion) Principle of relativity of scales

21 20 Laws of transformation of the scale variables From scale invariance to scale covariance

22 21 Dilatation operator (Gell-Mann-Lévy method): First order scale differential equation: Taylor expansion: Solution: fractal of constant dimension + transition:

23 22 Case of « scale-inertial » laws (which are solutions of a first order scale differential equation in scale space). Dependence on scale of the length (=fractal coordinate) and of the effective fractal dimension = D F - D T

24 23 Asymptotic behavior: Scale transformation: Law of composition of dilatations: Result: mathematical structure of a Galileo group ––> Galileo scale transformation group -comes under the principle of relativity (of scales)-

25 24 (Simplified case : ) Scale dependence of the length and of the effective scale dimension in special scale-relativity (log- Lorentzian laws of scale transformations)

26 25 Scale dynamics Scale laws that are solutions of second order partial differential equations in the scale space Least action principle in scale space ––> Euler Lagrange scale equations in terms of the « djinn » Resolution identified as « scale velocity »: Djinn (variable scale dimension) identified with « scale time »

27 26 (asymptotic) 'Scale dynamics': scale dependence of the length and of the effective scale-dimension in the case of a constant 'scale-force'

28 27 ‘Scale dynamics’: scale dependence of the length and of the effective scale-dimension in the case of an harmonic oscillator ‘scale-potential’

29 28 Scale dependence of the length and of the scale dimension in the case of a log-periodic behavior (discrete scale invariance) including a fractal / nonfractal transition.

32 31 Road toward Schrödinger (1): infinity of geodesics ––> generalized « fluid » approach: DifferentiableNon-differentiable

33 32 Road toward Schrödinger (2): ‘differentiable part’ and ‘fractal part’ Minimal scale law (in terms of the space resolution): Differential version (in terms of the time resolution): Case of the critical fractal dimension D F = 2: Stochastic variable:

34 33 Road toward Schrödinger (3): non-differentiability ––> complex numbers Standard definition of derivative DOES NOT EXIST ANY LONGER ––> new definition TWO definitions instead of one: they transform one in another by the reflection (dt -dt ) f(t,dt) = fractal fonction (equivalence class, cf LN93) Explicit fonction of dt = scale variable (generalized « resolution »)
