# Applied and Computational Mathematics

The Master of Science (MSc) in Applied and Computational Mathematics offers advanced education and research training in modern applied mathematics. Students admitted to the program will complete one of two program options.

## Admission Requirements

Applicants must satisfy the University admission requirements as stated in Graduate General Regulations 1.3 in the SFU Calendar. Applicants with backgrounds in areas other than mathematics (for example, a bachelor's degree or its equivalent in a related discipline such as statistics, engineering or physics) may be considered suitably prepared for these programs. Direct admission is only permitted into the thesis option.

## Program Requirements

This program consists of course work and requirements from either a thesis option for a minimum of 34 units or course option for a minimum of 32 units.

All course work is subject to approval by the supervisory committee and the departmental graduate studies committee.

Students must complete

a breadth requirement consisting of four courses from at least three different groups listed below

and an additional six units of graduate course work*

and the requirements from one of the two options below

*students who only complete 15 units of course work in the breadth requirement, must complete an additional unit of graduate course work

### Thesis Option

and a thesis

### Course Option

and an additional 10 units of graduate course work

### Groups

### Accelerated Master's

SFU students accepted in the accelerated master's within the Department of Mathematics may apply a maximum of 10 graduate course units, taken while completing the bachelor’s degree, towards the upper division electives of the bachelor’s program and the requirements of the master’s degree. For more information go to: https://www.sfu.ca/gradstudies/apply/programs/accelerated-masters.html.

## Program Length

Students are expected to complete the program requirements within six terms in the thesis option and five terms in the course option.

## Other Information

### Course Work

As per Graduate General Regulation 1.4.2, enrollment in courses from outside the Department of Mathematics requires approval of the course instructor.

### Satisfactory Progress

A cumulative grade point average (CGPA) of at least 3.5 is required to maintain good standing in the thesis stream. Any student unable to maintain the CGPA of at least 3.5 after their first two terms will be required to transfer at that time into the course option.

### Thesis

The thesis is submitted and assessed by the student’s examining committee as per GGR 1.10.

## Academic Requirements within the Graduate General Regulations

All graduate students must satisfy the academic requirements that are specified in the Graduate General Regulations, as well as the specific requirements for the program in which they are enrolled.
