Lectures on Symplectic Geometry

The target of those notes is to supply a quick creation to symplectic geometry for graduate scholars with a few wisdom of differential geometry, de Rham idea and classical Lie teams. this article addresses symplectomorphisms, neighborhood varieties, touch manifolds, appropriate nearly complicated constructions, Kaehler manifolds, hamiltonian mechanics, second maps, symplectic relief and symplectic toric manifolds.

Geometry and Physics

"Geometry and Physics" addresses mathematicians eager to comprehend glossy physics, and physicists eager to study geometry. It provides an advent to trendy quantum box idea and similar parts of theoretical high-energy physics from the point of view of Riemannian geometry, and an creation to fashionable geometry as wanted and used in smooth physics.

Lectures on the geometry of manifolds

An creation to the speculation of partially-ordered units, or "posets". The textual content is gifted in particularly a casual demeanour, with examples and computations, which depend upon the Hasse diagram to construct graphical instinct for the constitution of limitless posets. The proofs of a small variety of theorems is incorporated within the appendix.

Differential Geometry and Topology, Discrete and Computational Geometry

The purpose of this quantity is to provide an creation and review to differential topology, differential geometry and computational geometry with an emphasis on a few interconnections among those 3 domain names of arithmetic. The chapters supply the history required to start learn in those fields or at their interfaces.

Any Grassmannian can be embedded in a unitary group U(n). In Sect. 3, we see how Gauss transforms are a special case of K. Uhlenbeck’s construction [Uh] of adding a uniton, also called flag transform, which provides a method of modifying harmonic maps from a surface to the unitary group to get new ones. This process gives all harmonic 2-spheres in the unitary group as a ‘product’ of unitons. We 1991 Mathematics Subject Classification. Primary 53C42; Secondary 58E20. Key words and phrases.

1. Harmonic maps between Riemannian manifolds. Let (M, g) and (N, h) be smooth Riemannian manifolds and let ϕ : (M, g) → (N, h) be a smooth map between them. The energy or Dirichlet integral of ϕ over a compact domain D of M is defined by E(ϕ, D) = 1 2 D |dϕ|2 ωg EXPLICIT CONSTRUCTIONS OF HARMONIC MAPS 43 3 where ωg = volume measure and, for any p ∈ M , |dϕp |2 is the Hilbert–Schmidt square norm of the differential dϕp of ϕ at p. In local coordinates, this is given by β |dϕp |2 = g ij hαβ ϕα i ϕj .
