The authors prove that a local $n$-quasigroup defined by the equation x_{n+1} = F (x_1, ..., x_n) = [f_1 (x_1) + ... + f_n (x_n)]/[x_1 + ... + x_n], where f_i (x_i), i, j = 1, ..., n, are arbitrary functions, is irreducible if and only if any two functions f_i (x_i) and f_j (x_j), i \neq j, are not both linear homogeneous, or these functions are linear homogeneous but f_i (x_i)/x_i \neq f_j (x_j)/x_j. This gives a solution of Belousov's problem to construct examples of irreducible $n…

Quasigroup associativity and biased expansion graphs
We present new criteria for a multary (or polyadic) quasigroup to be isotopic to an iterated group operation. The criteria are consequences of a structural analysis of biased expansion graphs. We
Associativity in multiary quasigroups: the way of biased expansions
A multiary (polyadic, n-ary) quasigroup is an n-ary operation which is invertible with respect to each of its variables. A biased expansion of a graph is a kind of branched covering graph with an
In this paper, we define a new structure analogous to group, called partial group. This structure concerns the partial stability by the composition inner law. We generalize the three isomorphism
On some quasigroup cryptographical primitives
Using Vojvoda approach [34] we demonstrate that cryptographical primitives proposed in [26] are vulnerable relative to chosen ciphertext attack and chosen plaintext attack. We develop proposed in

This work reviews some known published applications of quasi- groups in cryptology and gives a review of the quasigroup, stream- cipher, secret-sharing system, and zero knowledge protocol applications.
Quasigroup based crypto-algorithms
Modifications of Markovski quasigroup based crypto-algorithm have been proposed, some of which are based on the systems of orthogonal n-ary groupoids.

Summary. For a complex polynomial, f: (C" + 1, 0)-.~ (C, 0), with a singular set of complex dimension s at the origin, we define a sequence of varieties -the L6 varieties, Af ), of f at 0. The
