- W2058076847 abstract "A Schauder is constructed for the space Ck(Tq) of k-times continuously differentiable functions on T , the product of q copies of the one-dimensional torus. This has the property that is also a for the spaces Cl(Tq), C2(Tq), ... Ckl(Tq), and an interpolating for C(Tq). 1. Notation and introduction. In this note we will simply say basis instead of Schauder . Let I denote the closed unit interval [0, 1]. Let T denote the interval I with the endpoints identified (i.e. T is the one-dimensional torus). For a natural number q, let f be a real-valued function on Iq or Tq. For a multi-index V= (Vl V2 ..,Vq), viE {0, 1, 2,. .}, let DVf denote the partial derivative fvlv,...vq We let Iv =v 1 vi denote the order of the partial derivative DVf. In case f is a function of a single variable, then Dmf will denote the mth derivative off, m= 1, 2, with the conventions Df= D'f and D?f=f. Let Ck(iq) denote the space of all real-valued functions on Iq for which all the partial derivatives of order no greater than k exist and are continuous. Writing this in symbols, we have Ck(lq) = {f: q -R; DVf is continuous for lvl < k} for k = 0, 1, 2, ... and q = 1, 2,.... Similarly, we have Ck(Tq) = {f: Tq -R; DVf is continuous for lv| ? k} for k = 0, 1, 2, ... andq = 1, 2,.... The linear spaces Ck(iq) and Ck(Tq) are Banach spaces when endowed with the norm Iflk(q,k)= E lDvIf II where 1. denotes the usual supremum norm and the sum extends over all multi-indices v with lvl <k. We use the natural conventions C(Tq)=C0(T), Ck(T) = Ck(Tl), etc. Ciesielski [3] and this author [7] independently resolved a problem of Banach by proving that the space Cl(12) has a basis. These proofs did not easily generalize Presented to the Society, January 22, 1971 under the title On the existence of Schauder bases in spaces Ck(Mn); received by the editors April 15, 1971 and, in revised form, July 15, 1971.
