Multipliers on modulation spaces

Key Points

• The research aims to explore the properties of multipliers within modulation spaces M p,q, particularly for certain function spaces.
• Studied multipliers defined on modulation spaces M p,q (R d )
• Focused on scenarios where 0 < p < 1
• Analyzed functions within B K space consisting of functions with bounded derivatives
• Identified that functions from B K are multipliers on M p,q under specified conditions.
• Established conditions related to the derivatives of functions that qualify as multipliers.
