Tóm tắt

Biến đổi Fourier Clifford (CFT) đã được chứng minh là một công cụ quan trọng trong phân tích Clifford. Mục đích của bài báo này là để suy ra một tương tự của các định lý Titchmarsh cho CFT đối với các hàm thoả mãn các điều kiện Lipschitz và Dini–Lipschitz trong không gian $$L^p(\mathbb {R}^{p,q},C\ell (p,q)), 1
