MATH 597F Introduction to Applied Mathematics II

Course Purpose:

    This is the second semester of a one-year introductory graduate course on applied mathematics. This is the second time we offer this course.

    The course is designed for graduate students who wish to learn some basic mathematical techniques that can be applied in their research and future career. Because of the rapid development of computer and network technologies, more and more mathematical techniques are used in more and more fields such as physics, chemistry, biology, economics, finance, engineering, meteorology, rheology, etc.. This course will cover some of the very basic mathematical techniques that are often not covered in regular undergraduate mathematical courses but are essential to the aforementioned application areas.

    This course has been designed by a group of computational and applied mathematicians from the department of mathematics with close collaborations with many professors from different departments at Penn State University. The syllabus of the course has been extensively debated and carefully designed to address the special needs of students with diversely different backgrounds. It is expected this course will be prerequisite for other basic graduate courses in computational and applied mathematics offered by the department of mathematics at Penn State. It is also expected that students who have taken this course sequence will have a solid foundation to take most other graduate courses on campus that involve the use of mathematical and computational techniques.
