Description
Summary:<p/> <p>Let <inline-formula><graphic file="1029-242X-2007-079816-i1.gif"/></inline-formula> be an Abelain semigroup, <inline-formula><graphic file="1029-242X-2007-079816-i2.gif"/></inline-formula>, and let <inline-formula><graphic file="1029-242X-2007-079816-i3.gif"/></inline-formula> be either <inline-formula><graphic file="1029-242X-2007-079816-i4.gif"/></inline-formula> or <inline-formula><graphic file="1029-242X-2007-079816-i5.gif"/></inline-formula>. We prove superstability of the functional equation <inline-formula><graphic file="1029-242X-2007-079816-i6.gif"/></inline-formula> in the class of functions <inline-formula><graphic file="1029-242X-2007-079816-i7.gif"/></inline-formula>. We also show some stability results of the equation in the class of functions <inline-formula><graphic file="1029-242X-2007-079816-i8.gif"/></inline-formula>.</p>
