Zassenhaus Assistant Professor 630 Mathematics Tower 231 18th Avenue Ohio State University Columbus, OH 43210 (614) 688-8733 (Office) czorn@math.ohio-state.edu |
At present, I am one of the Zassenhaus Assistant Professors at the Ohio State University's Mathematics Department. In May 2007, I graduated from the University of Maryland's Mathematics Department having completed a Ph.D in pure mathematics. I wrote my dissertation in the area of representation theory for p-adic symplectic groups and metaplectic under the guidance Prof. Stephen Kudla. I came to Maryland by way of the University of California, Santa Cruz where I received my B.A. in mathematics (June, 2002). Before attending UCSC, I also spent two years at Laney Junior College (Oakland, CA). For those of you that might have known me in a previous lifetime (e.g. high school), I attended high school at Chatfield Senior High in Jefferson County, CO.
My areas of interest in mathematics include the representation theory p-adic groups (and their covering groups) as well as automorphic forms. I present I am studying the non-vanishing of local theta lifts for Sp(4,F) and Mp(4,F) to various orthogonal groups using the local doubling integral. In the realm of automorphic forms, I am interested in integral representations of L-functions for various split groups.
Also, I got married on June 23, 2007 at St. John Neumann Catholic Church in Reston, VA. My wife's name is Colleen Courtney. She is originally from New Castle, Delaware, and works as a consultant for a firm based in Northern Virginia. She also finished her M.B.A. in the Spring of 2007 from George Mason University in Fairfax, VA. Additionally, my wife gave birth to our first child, a daugher named Molly Nora. She was born on May 26, 2009 (at 9:20 am), at the Ohio State University Hospital.

This table should be read as follows. If a problem is given by #.# (like 1.2), the first number refers to the chapter in the text and the second refers to the problem number at the end of the chapter. For instance, 1.2 refers to the second problem at the end of chapter one. If a problem is given by S#.# (like S1.4), then it comes from a supplemental problem set. The S# refers to the supplemental homework assignment number and the second # refers to the problem number. So S1.4 refers to the fourth problem on the first supplemental homework assignment. If a problem is given by N#.# (like N1.11), then the problems come from a set of supplemental notes. The N# refers to which set of notes and the second # refers to the problem number. The notes N1 are the Group Theory Notes which are also linked below.
Here are some links to the supplemental homework assignments.
NEW!--(10/12/09): The following is a link to a .pdf file that contains notes about basic abstract group theory. They were handed out in class and will be discussed during the week of 10/12/09-10/16/09: Group Theory Notes.
NEW!--(11/17/09): The following is a link to a .pdf file that contains notes about groups acting on sets. They were handed out in class and will be discussed after the second midterm: Group Actions on Sets Notes.
Tentative Exam Schedule--This section contains a tentative schedule for exams for the quarter. These dates are subject to change.
NEW!--(10/20/09): Due to the large number of students taking a Math 547 exam on October 23, 2009, we have rescheduled the first exam for Monday, October 26, 2009. It will cover Chapters 1-3 as well as the supplemental material on abstract group theory. The following is a link to the Exam 1 Review Problems in .pdf form. I will endeavor to post solutions to these problems by Friday, October 23, 2009.
NEW!--(10/22/09): The following is a link to the Exam 1 Review Problems Answer Key in .pdf form.
NEW!--(10/30/09): The following is a link to the Exam 1 Solutions in .pdf form. If you think that you have found an error in them, please email me so that I can correct them. I want folks to be able to use these solutions for study purposes, so their accuracy is important.
NEW!--(11/23/09): The following is a link to the Exam 2 Solutions in .pdf form. If you think that you have found an error in them, please email me so that I can correct them. I want folks to be able to use these solutions for study purposes, so their accuracy is important.
NEW!--(11/17/09): Due to the large number of students taking a Math 547 exam on November 20, 2009, we have rescheduled the second midterm for Monday, November 23, 2009. It will cover Chapters 4-6 as well as some supplemental material discussed since the first exam. The following is a link to the Exam 2 Review in .pdf form. Unlike the first exam review, there are no problems listed, but rather it suggests which topics one should study. It also suggests problems from the course text and supplemental exercises that one should study.

NEW!--(9/28/09): The following is a link to a .pdf file that contains the information about some textbooks that may serve as supplemental reading sources. As mentioned in class, these approach abstract algebra in a different way than the course text, but should still be useful when we talk about abstract group theory: Supplemental Textbook List.
NEW!--(11/02/09): I was very flattered by some folks request to see a picture of my daughter Moly in her first Halloween outfit (it's not a costume as much as it is a Halloween themed shirt and hat). So here are three pictures of Molly:
| Sitting in her carseat. | At home playing. | Close-up in her carseat. |
