چکیده

The aim of these lectures is to give a brief introduction to principal bundles on algebraic curves towards the construction of the moduli spaces of semistable principal bundles. The first lecture develops the basic machinery on principal bundles, their automorphisms. At the end of the first chapter, we give a proof of theorem of Grothendieck on orthogonal bundles. The second chapter, after developing the notions of semistability and stability gives a modern proof of Grothendieck’s theorem of classification of principal bundles on the projective line. The third chapter gives an outline of the construction of the moduli space of principal bundles on curves. The moduli space was constructed by A.Ramanthan in 1975. The method outlined here is from a new construction in [BS].

Comparing Lexical Bundles in Hard Science Lectures; A Case of Native and Non-Native University Lecturers

Researchers stated that learning and applying certain set of lexical bundles of native lecturers by non-native lecturers would help students improve their proficiency through incidental vocabulary input. The present study shed light on the lexical bundles in hard science lectures used by Native and Non-native lecturers in international universities with the main purpose of analyzing the structu...

A COVERING PROPERTY IN PRINCIPAL BUNDLES

Let $p:Xlo B$ be a locally trivial principal G-bundle and $wt{p}:wt{X}lo B$ be a locally trivial principal $wt{G}$-bundle. In this paper, by using the structure of principal bundles according to transition functions, we show that $wt{G}$ is a covering group of $G$ if and only if $wt{X}$ is a covering space of $X$. Then we conclude that a topological space $X$ with non-simply connected universal...

Lectures on Noncommutative Geometry

These Lectures are based on a course on noncommutative geometry given by the author in 2003. The lectures contain some standard material, such as Poisson and Gerstenhaber algebras, deformations, Hochschild cohomology, Serre functors, etc. We also discuss many less known as well as some new results such as noncommutative Chern-Weil theory, noncommutative symplectic geometry, noncommutative diffe...
