Yes, you can request authorship under a different spelling of your name. However, it's important to ensure that the spelling you use is consistently associated with your research output, especially if you intend to maintain a coherent author profile. When submitting your work or requesting authorship, clarify that the alternate spelling is an accepted variation of your name, and it may be helpful to include a note explaining this in your submission or correspondence with the publisher.

Claiming your authorship will be easier if you indicate the other spelling in your profile.
