Conditional Equations Related to Drygas Functional Equations
Abstract We determine the solutions of the conditional Drygas equation for functions f 1 and f 2 that satisfy ( y 2 + y ) f 1 ( x ) = ( x 2 + x ) f 2 ( y ) for all ( x , y ) ∈ ℝ 2 under the additional conditions y = x 2 , or y = log( x ), x > 0 or y = exp( x ).
