“…Under the assumption EFF =I= 8, Theorem 1.2. extends Theorem 7.2. of BRWWSKI [3] for finite linear vector optimization problems and Theorem III.2.a) of [6]. Example 111.4. of [6] shows the necessity of the assumption EFF + 0 in the above theorem. For ( p , q) E 'p and r > Q define MP (r, E ( p , 4)): min ( r , f ( x D subject to x E 2 andf,(x) 5 pi + E ( p , q) ql, i = 1, ..., I , which is equivalent to minimize ( r , f ( x ) ) on Q ( p , q).…”
