ISQGD Payments, Donations, Memberships & Events

Direct Payment Links

The following direct links may be used in ISQGD announcements, donation appeals, special session webpages, registration forms, flyers, and emails so that participants can go directly to the correct payment section.

Overview

The International Society in Quantization, Geometry, and Dynamics (ISQGD) is a U.S. IRS Recognized 501(c)(3) Public Charity dedicated to advancing mathematics, interdisciplinary education, outreach, and research worldwide. Contributions and membership payments support ISQGD academic programs, educational outreach, lectures, workshops, student activities, publications, website maintenance, academic archiving, certificate processing infrastructure, and the broader mission of ISQGD.

General ISQGD Annual Membership (AM)

General ISQGD Annual Membership uses the membership code AM. Example registration number: ISQGD-AM-2026-0001.

For each membership category, you may pay through PayPal Checkout, by credit/debit card directly through the ISQGD merchant payment portal or through PayPal Checkout, or via Zelle using the Zelle Tag payisqgd.

Club Memberships

Club memberships are separate from general ISQGD Annual Membership and are intended for participation in specific ISQGD club-based activities and informal speaking opportunities, subject to program guidelines.

Club membership payments may be made through PayPal Checkout, by credit/debit card directly through the ISQGD merchant payment portal or through PayPal Checkout, or via Zelle. Please include the correct club code, such as AM-MC or AM-PSC, when using Zelle or a merchant note field.

Special Session Registration Payment

ISQGD may collect registration fees for special sessions, conferences, workshops, mini-courses, certificate courses, student programs, and other approved academic events. Because different registration categories may have different fees, please select the payment button that matches your registration category. Each category includes a PayPal Checkout option and a credit/debit card payment option. Card payments may be processed directly through the ISQGD merchant payment portal or through PayPal Checkout.

These special-session registration links may be reused for different ISQGD special sessions and approved academic events. The event code or event title in the payment note is required for proper processing. If using Zelle or the merchant portal, include the same information in the memo, note, or description field whenever available.

Certificate Course Payments

ISQGD may offer certificate courses and structured educational programs. When a certificate course requires a course fee, please select the payment button corresponding to the appropriate certificate course. Since the course fee is the same for all participants within each certificate course, no registration category is required in this section unless the course announcement states otherwise.

Additional certificate courses may be added to this section as new ISQGD educational programs are announced. If paying through Zelle, include the certificate course title in the memo field.

Other ISQGD Payments

This section may be used for approved ISQGD payments that are not listed separately above, including workshop fees, mini-course fees, special program fees, affiliation-related payments, administrative processing fees, and other ISQGD academic or educational activities announced by the society.

If you are unsure which payment option to use, please contact office@isqgd.org before submitting the payment. For Zelle payments, include the same information in the memo field.
