Endpoint boundedness of toroidal pseudo-differential operators
Open MathematicsIn this note, we prove that the toroidal pseudo-differential operator is bounded from L∞(Tn){L}^{\infty }\left({{\mathbb{T}}}^{n}) to BMO(Tn){\rm{BMO}}\left({{\mathbb{T}}}^{n}) if the symbol belongs to the toroidal Hörmander class Sρ,δn(ρ−1)∕2(Tn×Zn){S}_{

Remarks on nonlocal trace expansion coefficients
, 2006 Dedicated to Krzysztof P. Wojciechowski on his 50th birthday In a recent work, Paycha and Scott establish formulas for all the Laurent coe-cients of Tr(APs) at the possible poles. In particular, they show a formula for the zero'th coecient at s = 0,
