Let I1 and I2 be intervals of real numbers. An interval game is played in this way: player 1 secretly selects x ∈ I1 and player 2 secretly and independently selects y ∈ I2. After x and y are revealed, payoffs are given by some predetermined function with domain I1 × I2. The payoff function for a zero sum interval game is a function A : I1 × I2 → R. This is interpreted to mean that the second pl...

We study infinite-dimensional analogs of classical Lie superalgebras over an algebraically closed field F zero characteristic. Let I be infinite set. For algebra M_∞ (I) × matrices a ground having finitely many nonzero entries, we consider the related superalgebra gl_∞ (I1, I2) and its commutator sl_∞ for disjoint union nonempty subsets I1 I2 set I; describe derivations I2).

Let i1 ≥ i2 ≥ i3 ≥ 1 be integers. An L(i1, i2, i3)-labelling of a graph G = (V, E) is a mapping φ : V → {0, 1, 2, . . .} such that |φ(u)− φ(v)| ≥ it for any u, v ∈ V with d(u, v) = t, t = 1, 2, 3, where d(u, v) is the distance in G between u and v. The integer φ(v) is called the label assigned to v under φ, and the difference between the largest and the smallest labels is called the span of φ. ...

As with many min-max characterizations, proving one of the inequalities is straightforward. For any U ⊆ S and I ∈ I1 ∩ I2, we have |I| = |I ∩ U |+ |I ∩ (S \ U)| ≤ r1(U) + r2(S \ U), since I ∩ U is an independent set in I1 and I ∩ (S \ U) is an independent set in I2. Therefore, maxI∈I1∩I2 |I| ≤ minU∈S (r1(U) + r2(S \ U)). The following important examples illustrate some of the applications of th...
