Dear Authors,

Please be advised that the online submission and manuscript management system for Contemporary Mathematics will be temporarily unavailable due to scheduled system maintenance.

During this period, we kindly request that all new manuscripts be submitted by email directly to the Editorial Office at cm@wiserpub.com.

The maintenance window will conclude on 28 October 2025 at 00:00 UTC. We apologize for any inconvenience caused by this necessary upgrade, which is intended to enhance system stability and improve service efficiency.

Thank you for your understanding and cooperation.

Sincerely,
