Voevodsky defined a motivic spectrum representing algebraic K-theory, and Panin, Pimenov, and Röndigs described its ring structure up to homotopy. We construct a motivic symmetric spectrum with a strict ring structure. Then we show that these spectra are stably equivalent and that their ring structures are compatible up to homotopy.

Voevodsky动力K理论谱的乘K理论模型。

Voevodsky定义了表示代数K理论的动力谱，Panin，Pimenov和Röndigs将其环结构描述为同伦。我们构造具有严格环结构的动力对称谱。然后，我们证明了这些光谱是稳定等效的，并且它们的环结构与同构体相容。
