The lecture is concerned with differential calculus for functions of several variables, convex analysis, and static optimization techniques (unconstrained, equality-constrained, and inequality-constrained problems)
as well as their application in business and economics.

3. Convexity
(convex sets, convex and concave functions in several variables)
4. Optimization of scalar valued functions

5. Optimization with equality constraints: Lagrange's method
