MATH 597F Introduction
to Applied Mathematics II
Course Purpose:
This is the second semester of a oneyear 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.
