Note Regarding the Three Editions of the DebnathMikusinski Book:
As you have probably discovered, there are three editions of the
main book we are using.
Since many of you have found a very inexpensive copy of the first
edition, but a few of you did buy the third edition (its seems very
few have the second edition), let me assure you that you can use
any of the three editions.
Here is a quick summary of the differences in the three editions:
 First Edition: Core book consisting of these eight chapters:
 Part I: Theory
 Normed Vector Spaces
 The Lebesgue Integral
 Hilbert Spaces and Orthonormal Systems
 Linear Operators on Hilbert Spaces
 Part II: Applications
 Applications to Integral and Differential Equations
 Generalized Functions and Partial Differential Equations
 Mathematical Foundations of Quantum Mechanics
 Optimization Problems and Other Miscellaneous Applications
 Second Edition: The primary change was the insertion of a new
Chapter 8, pushing the existing Chapter 8 to Chapter 9:
 Part II: Applications
 Wavelets and Wavelet Transforms
 Optimization Problems and Other Miscellaneous Applications
 Third Edition: The primary changes are slight expansions of some
of the sections; the most signficant change is probably the
inclusion of a section in Chapter 6 on Sobolev spaces.
In order to allow you to use any of the three editions, we need to
take care of two things:

Homework numbering differences between the three editions.
My homework problems will be of two types:
 Problems that are selfcontained in the HW PDF file.
 Problems that are assigned from the first edition exercises.
If you have one of the other two editions, in order to make sure
we are all looking at the same problems, I will post a scanned copy
of the set of exercises from the first edition with each homework.
Since nearly all of these exercises from the first edition appear
in all three editions (just with different numberings), this is
just a matter of dealing with the number differences in each
edition.
 We will talk about both Sobolev spaces (mainly 3rd edition) and wavelets
(both 2nd and 3rd editions). You do not need the book for this material;
my lecture notes will sufficient. I will make sure to assign problems
on that material without refering to the third (or second) edition.
COURSE DESCRIPTION:
The following is a brief description of the course.
Note that the UCSD catalog currently has a very dated description of
this course that was written a couple of decades ago.
Our goal for the course remain the same as for the
original course: provide graduate researchers in applied mathematics, physics,
science, and engineering with a more sophisticated and powerful set of
mathematical tools for performing their research.
However, we will update some of the topics to reflect changes in the
mathematical tools needed for modern science and engineering research;
obvious examples being the growing importance of simulation algorithms
over the last two decades, and the more recent emergence of data science
techniques in all areas of science and engineering research.
The prerequisites for the course remain the same as for the older
description of the course.

NOTE:
Hints for some of the homework problems above can be found in the back
of each of the three editions of the book.
The third edition contains more complete hints for some of the problems
that appear in both books (which are the ones I tried to focus on), so
you might want to borrow the third edition briefly if you have the
first (or second) edition just to look at the hints.

GRADES, HOMEWORKS, EXAMS, AND IMPORTANT DATES:
Course information, such as the planned lecture topics for the week,
any homework assignments, and so forth,
will be maintained on this class webpage.
Note that I sometimes make minor changes to both the lectures and
homework assignments as the quarter progresses, based on how much
I am able to cover in the lectures, and which directions we go based
partially on the interests of the students.
Therefore, CHECK THE WEBPAGE FREQUENTLY.
The course will be graded on attending most of the lectures,
doing some homework assignments,
and a final "take home" examination, according to the following guidelines:

Participation in Class (I.e., coming to most of the lectures): 

25% of grade 

Homeworks (3 written homeworks, each covering about 1/3 of the course): 

25% of grade 

Final Exam (take home exam)
WHICH IS POSTED
[ HERE ]


50% of grade 
The "participation in class" part of the course is that I simply want
you to try to come to most of the lectures; that will give you full
marks on that part of the grade.
(I will not actually take attendence; you are all adults.)
The "homeworks" will be based on the lectures, and will just give you
the opportunity to use some of the tools we go over in the lecture.
They will not be particularly timeconsuming; they are for your benefit.
Similar to the participation metric, if you make a good attempt on the
homework then I will give you full marks.
(I do not plan to formally grade the homeworks, but will try to give you
feedback if you feel you need it.)
The final will be a "take home" exam, which will simply be some problems
from the list of homework problems (that you will probably have already
attempted during the quarter), plus just a few other problems you will not
have seen.
I know some people made travel plans right after the final exam period,
so I will post this list of "take home final exam" problems to the class
website by the middle of the 10th week, so that you have plenty of time
to finish the take home exam by the time of the final.
In any case, please turn in the take home exam to me before the end
of finals week.
During the actual scheduled time of the final exam for 210A
(Monday December 7, 11:30a2:30p), I will be in my office and can
answer any lastminute questions about problems on the take home final.
(I will also have some coffee available for anyone who comes by...)
