• Cosine function
• integral-functional equation
• d'Alembert equation
• Wilson's equation
• Gajda's equation

In the present paper we deal with an integral generalization of a d'Alembert-type equation for unknown mappings defined on a locally compact Abelian group and taking their values in the field of complex numbers.
