Abstract

In this paper, the abstract multiplier theorems for 0 0 -sectorial and 0 0 -strip type operators by Kriegler and Weis [Math. Z. 289 (2018), pp. 405–444] are refined and generalized to arbitrary sectorial and strip-type operators. To this end, holomorphic Hörmander-type functions on sectors and strips are introduced, with even a finer scale of smoothness than the classical polynomial scale. Moreover, we establish alternative descriptions of these spaces involving Schwartz and “holomorphic Schwartz” functions. Finally, the abstract results are combined with a result by Carbonaro and Dragičević [Duke Math. J. 166 (2017), pp. 937–974] to obtain an improvement—with respect to the smoothness condition—of the known Hörmander-type multiplier theorem for general symmetric contraction semigroups.

全纯Hörmander-type扇形和条形上的泛函演算

本文讨论了由Kriegler和Weis提出的0 0扇形算子和0 0条形算子的抽象乘子定理。Z. 289 (2018)， pp. 405-444]被细化并推广到任意扇形和条形算子。为此，引入了扇形和条形上的全纯Hörmander-type函数，其平滑度比经典多项式尺度更精细。此外，我们建立了涉及Schwartz和“全纯Schwartz”函数的这些空间的替代描述。最后，将抽象结果与Carbonaro和dragi eviki [Duke Math]的结果结合起来。J. 166 (2017)， pp. 937-974]，以获得关于一般对称收缩半群的已知Hörmander-type乘数定理的光滑条件的改进。

期刊介绍： All articles submitted to this journal are peer-reviewed. The AMS has a single blind peer-review process in which the reviewers know who the authors of the manuscript are, but the authors do not have access to the information on who the peer reviewers are. This journal is devoted to research articles in all areas of pure and applied mathematics. To be published in the Transactions, a paper must be correct, new, and significant. Further, it must be well written and of interest to a substantial number of mathematicians. Piecemeal results, such as an inconclusive step toward an unproved major theorem or a minor variation on a known result, are in general not acceptable for publication. Papers of less than 15 printed pages that meet the above criteria should be submitted to the Proceedings of the American Mathematical Society. Published pages are the same size as those generated in the style files provided for AMS-LaTeX.
