Agenda: 1) Guest Speaker: Dr. Huseyin Yuce is from the The City University of New York (CUNY). The title of the talk he will be giving is "Can't Solve it? Perturb it!" Further detail is given in the abstract below.  2) Math Awareness Night! We will be reading excerpts from different books which reference mathematics, solve math competition problems, and play math pictionary with prizes! Student attendance at meetings is what's needed most for making the club vibrant and full of ideas and activities. ---------------------------------------------- C.

Numerical solutions also become   impossible in some cases. Therefore, many researchers are forced to   determine approximate solutions to the problems they are facing by   using perturbation techniques. In this talk, I’ll give a brief introduction to perturbation theory by   illustrating significant examples. The examples considered in this   talk are coming from algebraic equations, integrals, ordinary   differential equations, and finally partial differential equations   (specifically biharmonic eigenvalue problem).
