We study the behaviour of modified Hardy and Hardy–Littlewood operators in $\mathbf P$-adic Herz and Hölder–Besov spaces and in spaces close to $\mathbf P$-adic Hardy spaces and $\mathrm{BMO}$. We also establish a Titchmarsh-type equation for distributions and obtain an estimate for the multiplicative Fourier transform in $\mathbf P$-adic Hardy spaces.
Keywords: modified Hardy–Littlewood operator, modified Hardy operator, $\mathbf P$-adic Hölder–Besov spaces, $\mathbf P$-adic Hardy spaces
Mots-clés : $\mathbf P$-adic $\mathrm{BMO}$-space.
