2013-8-1 · similar product the symmetric Kronecker product denoted byA⊗sB has been the topic of recent research in the ﬁeld of semideﬁnite programming terest in the symmetric Kronecker product was stimulated by itsappear-ance in the equations needed for the computation of search directions forsemideﬁnite programming primal–dual interior–point algorithms. Onetypeof search direction is the AHO direction named after Alizadeh Haeberly andOverton. A generalization of this search direction is the Monteiro–Zhangfamily of directions. We will introduce those search directions and showwhere the symmetric Kronecker product appears in the derivation. Usingproperties of the symmetric Kronecker product we can derive conditions forwhen search directions of the Monteiro–Zhang family are uniquely deﬁned.We now give a short overview of this paper. In Section 2 we discuss theordinary Kronecker product
