Mabuchi solitons generalize Kähler–Einstein metrics on Fano manifolds, which constitute a Yau–Tian–Donaldson type correspondence with relative Ding stability. Comparing Kähler–Ricci solitons, there is distinct necessary condition for the existence. We show this can be implied by uniformly For this, we study inner product of $$\mathbb {C}^{*}$$ -actions equivariant test-configurations and obtain...

The conversion of the electrical energy into mechanical is usually realized by a motor, power electronics and cascade control. relative stability (?-stability), i.e., displacement its eigenvalues this system analyzed for drive with BLDC motor. influence changing basic parameters motor supply on operation considered. 4th order closed-loop transfer-function control presented, where boundaries coe...
