  • zeroth "assignment" due Friday 9/7, midnight: Email me
  • A brief sketch of the definition of the Riemann integral, as you learned it.
  • Whether or not you have previously studied the Lebesgue integral. If so, email a rough sketch of the definition.
  • This just needs to be a few lines. I'm looking for key words like step function, partition, approximation, zero set, measure, sigma-algebra, simple function, measurable function.
