David Ben-Chaim,Yaffa Keret,Bat-Sheva IlanyLet (M,g) be an n-dimensional Riemannian manifold of class C. and let P be a q-dimensional submanifold of M. A (solid) tube of radius r about P is the set.where T.(P) denotes the normal space of P at the point m. For small r the set.is a smooth hypersurface which we also call a tube.不连贯 发表于 2025-3-25 19:51:25

Heat, Cold and GeometryClassical and relativistic mechanics can be formulated in terms of symplectic geometry; this formulation leads to a rigorous statement of the principles of statistical mechanics and of thermodynamics.英寸 发表于 2025-3-26 06:32:13
Differential Deformations with Constant CoefficientsLet W be ℝ. and E(W,λ) be the space of formal series with coefficients in C. (W). A formal bi-differential operator P. is a bilinear map . with . where . is a usual bi-differential operator.色情 发表于 2025-3-26 09:10:24
Some Aspects of Theoretical Physics Relating to Harmonic MapsLet (M,g) be a compact Riemannian manifold without boundary, and consider an action which, for simplicity, we suppose has the form., where Φ is a section of a Riemannian fiber bundle π: E → M, and L: J. (E) → . possibly depends on the metric of E.离开就切除 发表于 2025-3-26 13:04:11
