M. J. Ablowitz & P. A. Clarkson: Solitons, Nonlinear Evolution Equations and Inverse Scattering
The aim of the course is to introduce the basic concepts of the mathematical aspects of Soliton Theory.
This will include the derivation and the introduction to the Korteweg-de Vries equation; the traveling
wave solution, Inverse Scattering Transform; N-soliton solution; Lax pair; Integrals of Motion; Hirota’s
bilinear method; Backlund Transform; AKNS (Ablowitz, Kaup, Newell and Segur) scheme; ZakharovShabat scheme; Painleve transcedents; Painleve conjecture; perturbation of solitons; adiabatic parameter
dynamics; Topological solitons, kinks and anti-kinks, breathers, phonons, skyrimions; chiral solitons.
The aim of this course is to serve as an introductory course to the more advanced course entitled Optical
Solitons that is offered in the Ph.D. program in Optics from the Department of Physics and PreEngineering. Students with a knowledge in this material can easily proceed to learn advanced materials
in optical solitons or topological solitons and other areas of Theoretical Physics.
Prerequisite: Advanced Calculus and Partial Differential Equations or equivalent. A successful student is
expected to gain a working knowledge of the covered material, so as to be able to (1) follow the
applications in the literature, (2) solve typical problems in the field, and (3) discuss adequately the termpaper material.

8. Needs Statement:
This course is needed for students pursuing a Ph.D. in all areas of theoretical physics and Applied
mathematics. The frameworks of Shallow Water Waves, optical pulses, topological solitons involve the
basic structure and properties of topological and non-topological solitons. The course material will cover
the following topics:
Korteweg-de Vries equation; the traveling wave solution, Inverse Scattering Transform; N-soliton
solution; Lax pair; Integrals of Motion; Hirota’s bilinear method; Backlund Transform; AKNS scheme;

10. List of Objectives of the Course:
(1) To provide an introduction to the body knowledge and techniques of integrability studies
of nonlinear evolution equations.
(2) To see how these techniques apply to the analysis of phenomena in Fluid Dynamics, Plasma Physics,
and Theoretical Physics.
(3) To learn how to identify those phenomena throughout theoretical physics and Applied Mathematics.
(4) To develop the problem-solving skills associated with the application of these methods in theoretical
physics, and learn how to extract experimentally verifiable information from such application.
11. Course Outline:
See the “Topical schedule” section in the attached brief syllabus.
12. Show how the proposed course fits into the curriculum or course sequence:
This course is an elective within the curriculum of the Ph.D. program in Theoretical Physics and Applied
Mathematics, and is indispensable for students focusing on fundamental physics. For an overview of prerequisite dependences and the course’s relation to other courses proposed herein, please see the attached
“Proposed Course Dependencies” chart.
13. Are there comparable courses in other departments?
No.
14. How will the students be affected by this course change?
This course provides the students an opportunity to increase their integration with the research program
of the Department of Applied Mathematics and Theoretical Physics, by understanding the mathematical
underpinnings of the techniques that are used in contemporary theoretical physics. This course will
improve students’ professional competence, employability in technical fields and ability to pass
professional examinations. Neither this course nor its prerequisites increase the total number of semester
hours in this curriculum or the number of credit hours required for graduation.
15. What effect will this new course have on College resource?
None: this course will not require new or additional resources or staffing.

16. How will the course benefit the College?
This course will address applications of ordinary and partial differential equations in various
areas of fundamental and applied physics, some of which lie at the foundation of numerous other
disciplines in science: engineering (e.g., optical fibers and lasers), physics (e.g. Nonlinear Optics).
17. How will the change affect the program?
This course will introduce students to a few select topics in “higher” mathematics and their application
in various branches of physics. This course will be one of the electives specific to the Ph.D. program in
Applied Mathematics and Theoretical Physics of this department. Besides providing such a crossdisciplinary broadening of knowledge for the students in this program, it also serves as a prerequisite to
Optical Solitons, also proposed herein.
