A high-order weighted positive and flux conservative method for the Vlasov equation
Takashi Minoshima, Yosuke Matsumoto
We present a high-order conservative, positivity-preserving, and non-oscillatory scheme for solving the Vlasov equation. The scheme attains formal fifth-order accuracy through a co…
