Abstract
Množenje matrik je v linearni algebri preprosta operacija, ki se pogosto pojavlja v rešitvah najrazličnejših problemov. Prav zato je bilo v iskanje hitrih algoritmov za množenje matrik vloženega že veliko dela. V diplomskem delu definiramo problem iskanja zgornje meje eksponenta matričnega množenja in razvijemo teorijo ranga in mejnega ranga bilinearnih preslikav. Predstavimo več algoritmov za hitro množenje matrik, ki slonijo na tej teoriji. Izbrane algoritme tudi implementiramo, jih primerjamo med seboj in ocenimo njihovo uporabnost v praksi.

Title:Fast matrix multiplication
Abstract:
Matrix multiplication is one of the most basic operations in linear algebra and thus very common in various scientific disciplines. Consequently, the computation complexity of matrix multiplication has been extensively studied. In this work, we define a problem of finding the upper bound for the exponent of matrix multiplication and present the theory of rank and border rank of bilinear maps. We describe multiple fast matrix multiplication algorithms based on this theory. In the end, we implement some selected algorithms, compare them, and discuss their value in practical applications.

Keywords:matrix multiplication, exponent of matrix multiplication, tensor rank, border rank
