Full textThe main contribution of this Ph.D. thesis is the elaboration of a new equivalence method, algorithmic, partly based on the Elie Cartan method, and applicable to Lie groups of finite or infinite dimensions. Its technical results are based on hundreds of calculation files, made using the Maple formal computing software. The thesis consists of 7 chapters, 6 of which are problem-oriented classifications, and 1 to a normal form ``à la Moser''.(1) A classification of Hessian rank 1 affinely homogeneous hypersurfaces Hn⊂ℝn+1 in dimensions n=2,3,4.All homogeneous hypersurfaces Hn⊂ℝn+1 are determined using of the power series equivalence method, which captures the invariants at the origin, which creates branches, and which infinitesimalizes the calculations. There are 6 terminal branches providing (families of) homogeneous models.(2) Another classification of affinely homogeneous surfaces S2⊂ℂ3.All homogeneous surfaces S2⊂ℂ3 are determined using of the power series equivalence method, which captures the invariants at the origin, which creates branches, and which infinitesimalizes the calculations. There are 12 terminal branches providing (families of) homogeneous models.(3) A classification of affinely homogeneous surfaces S2⊂ℝ4.Using the same method, we determine all surfaces S2⊂ℝ4 which are affinely homogeneous.There are 103 terminal branches providing homogeneous (families of) surface models, some of which are parameterized by real algebraic varieties, especially in the case of simply transitive.(4) A classification of affinely homogeneous hypersurfaces S3⊂ℝ4 of constant rank 2 Hessian.By always applying the same method, we find 34 terminal branches providing (families of) homogeneous surface models S3⊂ℝ4 of rank 2 Hessian matrix. Again, simply transitive models are often parameterized by real algebraic varieties.(5) A local normal form for the ordinary differential equations of 2nd order under the action of fiber-preserving point transformations.We study the equivalence problem of real analytic second order ordinary differential equationsyxx=J(x,y,yx) under fiber-preserving transformations x→φ(x), y→ψ(x,y) using the Moser normal form method.(6) Another classification of homogeneous 2nd order ordinary differential equations under the action of fiber-preserving point transformations.All 2nd order ordinary differential equations are determined under the action of fiber-preserving transformations using the equivalence method of power series. In this delicate context, the ambiguity group is of infinite dimension. There are 7 terminal branches providing homogeneous (families of) models, which can be parameterized by a certain algebraic variety.(7) A classification of homogeneous 2nd order 5-dimensional PDEs under the action of fiber preserving point transformations.Still with an adaptation of the method of equivalence of the power series to the context of the infinite dimension, we find 24 terminal branches providing (families of) homogeneous multiply transitive models

Full textWe also characterize invariantly under point transformations some equivalence classes of parabolic quasi-linear second order partial differential equations, and examine their point symmetry groups. We are able to make our characterizations by proving a reduction theorem for principal fibre bundles.

Full textThe first part of the thesis consists of calculations around Siu's effective termination of Kohn's algorithm. The second part of the thesis studies the CR real hypersurfaces in complex spaces and calculates various explicit invariants using Cartan's equivalence method to study CR-umbilical points
Ta, The Anh. "Topics in Complex and CR geometry." Thesis, université Paris-Saclay, 2020. http://www.theses.fr/2020UPASM007.
Full textThis memoir contains research results in complex geometry and CR geometry. The topics include degree bounds for hypersurfaces in Kobayashi hyperbolicity related problems, equivalence problems and construction of normal forms for certain classes of Levi degenerate 5-dimensional hypersurfaces in complex spaces and investigations on the vanishing locus of Cartan CR curvatures on boundaries of some 3-dimensional CR manifolds. The common theme is the use of higher jets in diverse geometric situations to investigate invariants of geometric objects, and the extensive use of symbolic computational programs to help with complicated calculations
