Let G be a graph embedded in a surface and let F be a set of even faces of G (faces bounded by a cycle of even length). The resonance graph of G with respect to F, denoted by R(G;F), is a graph such that its vertex set is the set of all perfect matchings of G and two vertices M1 and M2 are adjacent to each other if and only if the symmetric difference M1 ⊕M2 is a cycle bounding some face in F. ...

Resum En aquest article es presenta l’evolució que ha sofert recentment l’educació a distància des d’una nova perspectiva, la ciència del web, que estudia com el web ha evolucionat tecnològicament, però també socialment i organitzativament. El web, una solució tecnològica inicialment pensada per a compartir informació, és avui dia present en totes les activitats quotidianes, en qualsevol àmbit ...

In this talk I discuss two relations between normative reasoning and formal argumentation. First I consider formal argumentation as a kind of normative reasoning. An attack of argument A on argument B is interpreted either as “either A is not accepted or B should be accepted” or as “A and B cannot both be accepted, and it is preferred to accept A over B”. The difference between the two interpre...

The processing performed by a feed-forward neural network is oft en int erpreted through use of decision hyperplanes at each layer. T he adaptation process, however, is normally explained using the picture of gradient descent of an error land scape. In thi s paper t he dynamics of t he decision hyperplanes is used as t he model of the adaptat ion process. An electro-mechanical analogy is drawn ...

a positive integer $n$ is called a clt number if every group of order $n$ satisfies the converse of lagrange's theorem. in this note, we find all clt and supersolvable numbers up to $1000$. we also formulate some questions about the distribution of these numbers.

the zarankiewicz number z(b; s) is the maximum size of a subgraph of kb,b which does not contain ks,s as a subgraph. the two-color bipartite ramsey number b(s, t) is the smallest integer b such that any coloring of the edges of kb,b with two colors contains a ks,s in the rst color or a kt,t in the second color.in this work, we design and exploit a computational method for bounding and computin...

a dominating set $d subseteq v$ of a graph $g = (v,e)$ is said to be a connected cototal dominating set if $langle d rangle$ is connected and $langle v-d rangle neq phi$, contains no isolated vertices. a connected cototal dominating set is said to be minimal if no proper subset of $d$ is connected cototal dominating set. the connected cototal domination number $gamma_{ccl}(g)$ of $g$ is the min...
