The author studies sequence spaces associated with holomorphic functions on the unit disc, identifying any such function with his Taylor sequence. The author's abstract: We define and investigate relative solidity for sequence spaces, and use it to study spaces of holomorphic functions on the unit disk and related coefficient multiplier spaces. In particular, we find the multipliers \((l(u, v), H(p, q, t))\) and \((H(p, q, t)\), \((l(u, v))\) for many values of the parameters \(u\), \(v\), \(p\), \(q\), \(t\).
