Some results on packing in Orlicz sequence spaces
We present monotonicity theorems for index functions of N-fuctions, and obtain formulas for exact values of packing constants. In particular, we show that the Orlicz sequence space l (N) generated by the N-function N(v) = (1 +jvj) ln(1 +jvj) jvj with Luxemburg norm has the Kottman constant K(l (N) ) = N 1 (1)=N 1 (1=2), which answers M. M. Rao and Z. D. Ren's (8) problem.
