Counterexamples for multi-parameter weighted paraproducts 多参数加权副积的反例

We build the plethora of counterexamples to bi-parameter two weight embedding theorems. Two weight one parameter embedding results (which is the same as results of boundedness of two weight classical paraproducts, or two weight Carleson embedding theorems) are well known since the works of Sawyer in the 80’s. Bi-parameter case was considered by S. Y. A. Chang and R. Fefferman but only when underlying measure is Lebesgue measure. The embedding of holomorphic functions on bi-disc requires general input measure. In [9] we classified such embeddings if the output measure has tensor structure. In this note we give examples that without tensor structure requirement all results break down. Résumé. Dans le présent article, nous construisons une pléthore de contre-exemples aux théorèmes de plongements à deux poids et à deux paramètres. Les résultats de plongement à un paramètre et à deux poids (qui sont la même chose que les résultats de paraproduits bornés classiques à deux poids) sont bien connus depuis les travaux de Sawyer dans les années 80. S. Y. A. Chang et R. Fefferman ont examiné le cas des deux paramètres, mais uniquement lorsque la mesure sous-jacente est la mesure de Lebesgue. Le plongement de fonctions holomorphes sur le bi-disque nécessite une mesure générale en entrée. Dans [9], nous avons classé ces plongements lorsque la mesure obtenu en sortie a une structure tensorielle.

我们建立了大量的双参数两个权重嵌入定理的反例。自80年代Sawyer的作品以来,两个权一参数的嵌入结果(与两个权经典副积的有界性结果或两个权Carleson嵌入定理相同)是众所周知的。S. Y. A. Chang和R.

We completely compute the mod 2 Margolis homology of the Dickson algebra Dn , i.e. the homology of Dn with the differential to be the Milnor operation Q j , for every n and j . The motivation for this problem is that, the Margolis homology of the Dickson algebra plays a key role in study of the Morava K-theory K ( j )∗(BSm ) of the symmetric group on m letters Sm . We show that Pengelley–Sinha’s conjecture on H∗(Dn ;Q j ) for n ≤ j is true if and only if n = 1 or 2. For 3 ≤ n ≤ j , our result proves that this conjecture turns out to be false since the occurrence of some “critical elements” hs1 ,...,sk ’s of degree (2 j+1 −2n )+∑ki=1(2n −2si ) in this homology for 0 < s1 < ·· · < sk < n and k > 1. Résumé.

La motivation pour cette étude est le rôle clé joué par cette homologie dans l’étude de la K-théorie de Morava K ( j )∗(BSm ) du groupe symétrique Sm en m lettres. Nous montrons que la conjecture de Pengelley–Sinha sur H∗(Dn ;Q j ) pour n ≤ j est vraie si et seulement si n = 1,2. Pour 3 ≤ n ≤ j notre résultat montre que la conjecture est fausse à cause de l’occurence d’éléments « critiques » hs1 ,...,sk de degré (2 j+1 − 2n )+∑ki=1(2n − 2si ) dans cette homologie pour 0 < s1 < ·· · < sk < n et k > 1.
