Note on the lifespan estimate of solutions for non-gauge invariant semilinear massless semirelativistic equations with some scaling critical nonlinearity
Kazumasa Fujiwara
In this manuscript, in the scaling critical case, a lifespan estimate of solutions to the Cauchy problem for non-gauge invariant semilinear semirelativistic equations is cons…

Remark on the Chain rule of fractional derivative in the Sobolev framework
Kazumasa Fujiwara
A chain rule for power product is studied with fractional differential operators in the framework of Sobolev spaces. The fractional differential operators are defined by the Fourie…
