Construction of Affine Super Yangian

In this paper, we define the affine super Yangian $Y_{{\epsilon }_1,{\epsilon }_2}(\widehat{\mathfrak{s}\mathfrak{l}}(m\mathrm{\mid }n))$ with a coproduct structure. We also obtain an evaluation homomorphism, that is, an algebra homomorphism from $Y_{{\epsilon }_1,{\epsilon }_2}(\widehat{\mathfrak{s}\mathfrak{l}}(m\mathrm{\mid }n))$ to the completion of the universal enveloping algebra of $\widehat{\mathfrak{g}\mathfrak{l}}(m\mathrm{\mid }n)$.
