During the Spring term of 2013, Linear Algebra will be coordinated by Prof. Chris Jankowski, chrisj@cims.nyu.edu.

Welcome to Linear Algebra!

Linear Algebra is an area of mathematics devoted to the study of structure-preserving operators on special sets (linear operators on vector spaces).  Linear algebra is a cornerstone of any mathematics curriculum for two very important (and related) reasons: 1) The theory of linear algebra is well understood and so a first step in many areas of applied mathematics is to reduce the problem into one in linear algebra.  2) The spaces and operations studied in the subject are commonplace in many different areas of mathematics, science, and engineering.

Over the semester we will study many topics that form a central part of the language of modern science:

  • Formulate, solve, apply, and interpret systems of linear equations in several variables;
  • Compute with and classify matrices;
  • Demonstrate elementary facts in abstract vector spaces;
  • Decompose linear transformations according to their spectra (eigenvectors and eigenvalues)
  • Use length and orthogonality in each of the above contexts.
  • Other topics as time permits

The material we take up in this course has applications in physics, chemistry, biology, environmental science, astronomy, economics, statistics, and just about everything else. We want you to leave the course not only with computational ability, but with the ability to use these notions in their natural scientific contexts, and with an appreciation of their mathematical beauty and power.
