Higher-derivative field theories extend conventional frameworks by incorporating terms with higher-order derivatives in their equations of motion. This formulation not only enriches the mathematical ...
In this paper we prove local existence of solutions of the nonlinear heat equation ${\mathrm{u}}_{\mathrm{t}}=\mathrm{\Delta }\mathrm{u}+{\left|\mathrm{u}\right ...
We characterized the distances from Bloch functions to some Möbius invariant spaces by high order derivatives. Moreover, the boundedness and compactness of the products of composition and di ...
