The explicit formula for Möbius function of Fibonacci cobweb poset P is given here for the first time by the use of Kwaśniwski’s definition of P in plane grid coordinate system [1]. 1 Fibonacci cobweb poset The Fibonacci cobweb poset P has been introduced by A.K.Kwaśniewski in [3, 4] for the purpose of finding combinatorial interpretation of fibonomial coefficients and their reccurence relation...

" By William Gibson. Martin Seeker 6? Warburg Ltd. 15/-. Perhaps it is professional prejudice, but psychiatric interviews in novels are seldom convincing and The Cobweb is not an exception. The theme, however, need not have been set in a psychiatric hospital. Almost any setting could have been used, and in itself it is interesting and exciting. The book gives a lively account of interpersonal t...

The characterization of Fibonacci Cobweb poset P as DAG and oDAG is given. The dim 2 poset such that its Hasse diagram coincide with digraf of P is constructed. 1 Fibonacci cobweb poset The Fibonacci cobweb poset P has been invented by A.K.Kwaśniewski in [1, 2, 3] for the purpose of finding combinatorial interpretation of fibonomial coefficients and eventually their reccurence relation. In [1] ...

Laboratory experiments of commodity markets have used the Cobweb design to investigate market dynamics. The predicted cycles of the Cobweb theory did not occur. Arango (2006) adds complexity and realism to the Cobweb model and observes stronger fluctuations and autocorrelation. He shows that these fluctuations are quite symmetric and similar to the behaviour observed in one category of markets....

We present the material analysis of scaffolding silk from the cobweb of the black widow spider Latrodectus hesperus. 30 strands were tested from the webs of nine spiders. Strands were stretched at 0.211 mm/s as force and extension were recorded. Cross-sectional area was measured under 1000 x oil-immersion light microscopy. The stress strain curve shows that cobweb silk is a distinct material fr...

The Fibonacci cobweb poset P has been introduced by A.K.Kwaśniewski in [3, 4] for the purpose of finding combinatorial interpretation of fibonomial coefficients and their reccurence relation. At first the partially ordered set P (Fibonacci cobweb poset) was defined via its Hasse diagram as follows: It looks like famous rabbits grown tree but it has the specific cobweb in addition, i.e. it consi...

A class of new type graded infinite posets with minimal element is introduced. These so called cobweb posets proposed recently by the present author constitute a wide range of new noncommutative and nonassociative prefab combinatorial schemes‘ examples with characteristic graded sub-posets as primes. These schemes are defined here via relaxing commutativity and associativity requirements impose...
