Class times    image

We will meet MWF 10:00-11:00am in S 115.


Technology requirements

You should have a scanner or certain smartphone apps that allow you to scan your handwritten homework into a pdf file. Alternatively, certain tablets and tablet apps allow you submit your written work directly from the tablet.


Recordings of class

Students may not record all or part of class, livestream all or part of class, or make/distribute screen captures without advanced written consent of the instructor. If you have or think you may have a disability such that you need to record class-related activities, please contact the Justin Dart Jr. Student Accessibility Center. If you have an accommodation to record class-related activities, those recordings may not be shared with any other students, whether in this course of not, or with any other person or on any other platform. Classes may be recorded by the instructor. Students may use instructor's recordings for their own studying or notetaking. Instructor's recordings are not authorized to be shared with anyone without the prior written approval of the instructor. Failure to comply with requirements regarding recordings will result in a disciplinary referral to the Dean of Students Office and may result in disciplinary action.

Contact

Dr. Vershynina (you should refer to me as either Doctor/Dr. or Professor/Prof. followed by my last name)

Email: anna@math.uh.edu

Please include "MATH 6321" in the subject, so that your email won't be regarded as spam. For security reasons I will reply only to emails sent from official UH emails (i.e. ending in "uh.edu").

When writing an email, make sure it adheres to the protocol of formality, which is standard in academia. Read more about it here, for example.

Normally, I answer urgent emails within one-two business days. Generally, I do not repeat information that can be found on this website or was communicated in class. If I do not respond to your email within two working days, please resend the email. If you again do not hear from me within one more working day, it is likely that your email is not coming through and you should speak with me before or after class. It is your responsibility to ensure that I am aware of issues you may have with the course; failure to effectively initiate timely communication is not a valid basis for a grade grievance and cannot be used as such.

Bring comments or complaints to my attention as soon as possible. Don't wait until the end of the semester to bring up a matter which we could deal with and solve early on.

UH Email

Email communications related to this course will be sent to your Exchange email account which each University of Houston student receives. The Exchange mail server can be accessed via Outlook, which provides a single location for organizing and managing day-to-day information, from email and calendars to contacts and task lists. Exchange email accounts can be accessed by logging into Office 365 with your Cougarnet credentials or through Acccess UH. They can also be configured on IOS and Android mobile devices. Additional assistance can be found at the Get Help page.

UH policy states that all required written notices shall be addressed to the student via their UH email. Notices properly addressed and so sent shall be presumed to have been received by the student. Thus, you are responsible for the content in emails sent to your UH account, regardless if your external (non-UH) email provider filters or blocks. Emails lost to external providers shall not be used as a justification to claim faculty are unresponsive, to appeal grades, etc.

Quizzes image

Quiz will be held every couple of weeks, see calendar below. Changes can occur with an advance notice (at least 2 days). Most of the quizzes will consists of one/two problems not previously discussed in class, and will be 10-15 min long held during the class. One lowest grade will be dropped to accommodate any unforeseen life circumstances forcing you to miss the quiz. Excused absence of the second missed quiz will only be granted in accordance with the UH Absence Policy, with proper and timely provided documentation.

Quizzes will be graded using Gradescope system. Since this is an outside of the UH website, you are not required to use it. You must inform me during the first week if you opt out of using the system and alternative arrangements will be made for you. Information below is directed to those students wishing to use Gradescope system.

You have one week after your grade is posted to submit a regrade request if you believe there was a mistake with your grading. Along with your request in Gradescope, you must write me an email providing an explanation for a regrade (e.g. your solution was correct, but was marked as incorrect). Requests to change the rubrics will be ignored.

When enrolling yourself in Gradescope, use code: 4V5Y2B . When entering your name, please enter the first 3 letters of your LAST, then first 3 letters of your FIRST name. For example, for a name John Smith, a student should enter "Smi Joh". As your ID number, enter the last 3 digits of your student ID. You are free to use any email with Gradescope, it does not have to be your UH email.

Regrade Requests

You have one week after your grade for Midterm or Quiz is posted to submit a regrade request if you believe there was a mistake with your grading. The deadline for the Final regrade will be communicated by email after the exam is graded.



Missed Class

If you miss class for whatever reason, you are responsible for all material covered, all lecture material presented in class, and all announcements made in class. When you miss a class, here are the steps to take to catch up with the material:

  1. Check the calendar below to see what chapter was covered in class. Calendar is updated a few hours after the class.

  2. Check Teams for any available notes covering this material. I will try to post some notes on Teams for each chapter, but they may not fully or accurately reflect what was done in class. If there are no notes on Teams, this means they are not available for this chapter/section/class.

  3. Study the corresponding chapter in the textbook.

  4. Contact your classmates for their lecture notes and to find our about any announcements made in class. Your classmates are the best resource for catching up with the material and for jointly solving homework problems.



Honor Code Statement

Students are expected to adhere to the University of Houston Graduate Academic Honesty Policy on all exams and tests. Academic honesty is taken very seriously and, in the cases of violations, penalties may include suspension or expulsion from the University of Houston."

Preliminary Exams

Preliminary exam on the Theory of Real Variables is based on the material covered in two semesters of this class: 6320 and 6321. The exam mainly tests problem solving skills, which rely on the knowledge of definitions, statements and proofs of theorems covered in class. Full list of definition and theorems can be found here
