We introduce a class of operators, called l-Hankel operators, as those that satisfy the operator equation S g X -XS=lX, where S is the unilateral forward shift and l is a complex number. We investigate some of the properties of l-Hankel operators and show that much of their behaviour is similar to t

In the classical risk model, an insurer pays claim costs at the instants of their occurrence and he receives premiums in a continuous linear way. If there is no initial risk reserve, it is known that, under specified assumptions, the probability of non-ruin in the finite interval (o, t) equals wher

## Abstract Shelah has shown (see [1]) that the number __d__, the smallest cardinality of a dominating family, is less than or equal to the number __i__, the smallest cardinality of a maximal independent family on ω. This was done using a downward Löwenheim‐Skolem argument. Thus it is interesting t
