In this chapter of the Ashwamedha Parva of the Mahabharata, Krishna brings Abhimanyu's son Parikshit back to life, after he is born stillborn as a result of Ashwatthama's Brahmastra (which I discuss here). Here is what Krishna says in order to bring the boy back to life:
Never before have I uttered an untruth even in jest. Never have I turned back from battle. (By the merit of those acts) let this child revive! As righteousness is dear to me, as Brahmanas are specially dear to me, (by the merit of that disposition of mine) let Abhimanyu's son, who is born dead, revive! Never hath a misunderstanding arisen between me and my friend Vijaya. Let this dead child revive by that truth! As truth and righteousness are always established in me, let this dead child of Abhimanyu revive (by the merit of these)! As Kansa and Kesi have been righteously slain by me, let this child revive today by that truth!
My question who is this "Vijaya" who was the friend of Krishna? Vijaya means victory, so I'm guessing that it refers to Arjuna. Another friend of Krishna was Sudama (whom I discuss here), but I doubt he would be called Vijaya.
Are there any commentaries on the Mahabharata that address who Krishna is referring to here?
