Abstract
Pfaffian matrice je u teoriji grafova iznimno važan jer se koristi za prebrojavanje savršenih sparivanja u grafu. Da bi to bilo moguće, nužno je da su grafovi planarni. Zato smo uveli pojam planarnog grafa te pokazali neke osnovne pojmove i tvrdnje o sparivanjima. Za prebrojavanje savršenih sparivanja, koristili smo vezu između determinante i Pfaffiana matrice \(det(B) = (P f(B))^2\) koju je prvi ustanovio Cayley 1849. godine. Kako bi si još olakšali prebrojavanje uvodi se pojam Pfaffian orijentacija, koja naglašava kakva orijentacija mora biti u nekom grafu da bi mogli prebrojavati savršena sparivanja. Jedna od glavnih primjena Pfaffiana dobiva svoj smisao na pravokutnim mrežama, jer su one primjenjive u fizici, gdje ih koristimo kod problema prelazaka dvoatomskog plina u kristalni supstrat.
Abstract (english)
Pfaffian of a matrix is in graph theory very important since it is applicable for counting perfect matchings in a graph. To make this possible, graphs have to be planar. Because of that, we introduced notion of a planar graph and some basic terms and theorems on matching. For counting perfect matching in graphs, we used connection between a determinant of a matrix and its Pfaffian \(det(B) = (P f(B))^2\) which was established by Cayley in 1849. To make it even simple to count, we introduced the term Pfaffian orientation. Which highlights what orientation must be in graph for counting perfect matching. The key applications of Pfaffian is in rectangular grids. Because rectangular grids is applicable in physics, where we use them in the problem of the transition two-atom gas in a crystalline substrate.
