## Contact and submission status

Contact Liu Yuan with research feedback, recalculations, counterexamples or collaboration proposals concerning ASD. A precise question is welcome, as is a complete reproducible contribution. No title, institutional affiliation or completed solution is required.

Public contact email:

<ContactAddress />

The email controls above let you copy the address or prepare a message in your own email application. Review and send the message yourself. This website does not send it, provide a submission receipt or promise a response time.

## What to include

For brief feedback, identify the page, equation or OP ID and the specific point to check, with your reason. You can ask before completing a recalculation; state how far you have checked.

For a complete contribution, include premises, inputs and parameter sources, derivation or execution steps, results, errors and unresolved checks. Give versions, the execution environment and usage conditions for code and data. Separate added assumptions from existing website results. Counterexamples, failed attempts and non-discriminating results are useful; do not present an unverified idea as a completed solution.

A useful subject is “ASD research feedback | page or OP ID | short question”. Choose the name and contact details you wish to share. An affiliation is optional.

## Local drafts and privacy

The [local research draft](/en/collaborate/contact#research-draft) helps you organize and download material in the current browser. Filling in, copying or downloading a draft does not send an email, submit a result or obtain project acknowledgment. It does not automatically publish the draft or pass it to AI.

Check the message and attachments before sending, and share only material you intend the recipient to receive. An emailed draft does not automatically become public website content. Public attribution, the scope of material to publish and any further use require separate agreement.
