Math 131AB is the core undergraduate course sequence in  mathematical analysis. The aim of the course is to cover the basics of  calculus, rigorously. Along with Math 115A, this is the main course in which  students learn to write logically clear and correct arguments. 
        There is an honors sequence Math 131AH-131BH running parallel to 131A-131B  in fall and winter. 131AH: Rigorous treatment of the foundations of real  analysis, including construction of the rationals and reals; metric space  topology, including compactness and its consequences; numerical sequences and  series; continuity, including connections with compactness; rigorous treatment  of the main theorems of differential calculus. 131BH: The Riemann integral;  sequences and series of functions; power series, and functions defined by them;  differential calculus of several variables, including the implicit and inverse  function theorems.
        Math 131C is a special topics analysis course offered in the spring that is  designed for students completing the honors sequence as well as the regular  131AB sequence. It traditionally covers Lebesgue measure and integration
        Math 131A is offered each term, while 131B is offered only Winter and  Spring.
