... (28) This i dentity is of the involution–type. Proof. The left–hand side of (28) corresponds to superpositions of matchings µ ∪ ν of non–vanishin g weight with red vertices R ∪ W and blue vertices ... image of χ is precisely the set of superpositions of matchings corresponding to the right hand side of (28). This yields immediately the following generalization of a res...

... of q, we move one element from the end of the left list into the stack, and when we encounter an element of p, we move the top of the stack to the beginning of the right list. If an element of ... given time, the number of elements of p added is the same as the number of elements that have entered the stack, the number of elements of q added is the same as the number...

... level numbers of the leaves of an extended binary tree. She provided a recurrence relation and table of the number of trees classified according to their height and their number of leaves. We ... 2]]. Proof. Let the node n be in the subtree h or the super-node, call it y, that is the parent of subtree h. Let x be the root of that subtree and denote the left and right subt...

... must be the image via L of some element of the center of U(gl(m)), and also the image via R of some element of the center of U(gl(n)). The Capelli identity (1.19) with A = X and B = ∂ gives an explicit ... = 0 and (4.7) = β 2 = 0. ✷ Proof of Proposition 1.5. Let us first consider the case in which A is antisymmetric off-diagonal and we seek a result with col-per. We foll...

... This completes the proof of (i). By a similar discussion as in the proof of (i), we may also show that (ii)-(iv) are true. We omit the procedure here. This completes the proof of Lemma 2.9. We know ... − v and G −xy instead of G −{v} and G −{xy}, respectively. Denote the neighborhood of v ∈ V (G) by N(v) = N G (v); and let N[v] = N(v)∪{v}. Throughout the paper we denote by P n...

... values of R combined with larger values of D RSU would lead to longer multi-hop paths, in terms of number of traversed nodes, and therefore lower effective bandwidths. Only for R = 150 m and in the ... < u  and χ 2 (w) is a chi- square variable with w degrees of freedom. Since the probability P (i) of having a connected chain of i hops is given by (1−e −βR ) i e −βR , t...

If we denote s k the state of the ... N is the number of particles, and c is the inverse of the evidence factor in the denominator of (1). As opposed to importance sampling, a record of the current state is kept,...
