Abstract(in English) | It is known that the condition m≧2n-3 is necessary for a 2-dimensional bar-joint framework with n pin-joints and and m barsof fixed lengths to be rigid. Also the condition m≧3n-6 isnecessary for a 3-dimensional bar-joint framework to be rigid. Thisis a classical result discovered by Maxwell in 1864. This conditiontells us that the rigidity of a framework relies on its topology(incidence relationship between joints and bars). In fact, about ahundred years later, Laman proved in 1970 that the rigidity of a2-dimensional bar-joint framework is determined by its incidencerelationship. A main theme of combinatorial rigidity theory is toanalyze and clarify the rigidity of certain structural models. Theconsequence of combinatorial rigidity theory gives us fundamentalknowledge about structures and since the late 90's it has beenapplied to various fields such as mechanical design, dynamicsimulation of proteins, intelligent CAD system, sensor networklocalization. In this talk, I will first give a basic theory ofcombinatorial rigidity and then touch on applications to theelucidation of protein functions and to architectural design. |
