dynamic coloring of graph
در این پایان نامه رنگ آمیزی دینامیکی یک گراف را بیان و مطالعه می کنیم. یک –kرنگ آمیزی سره ی رأسی گراف g را رنگ آمیزی دینامیکی می نامند اگر در همسایه های هر رأس v?v(g) با درجه ی حداقل 2، حداقل 2 رنگ متفاوت ظاهر شوند. کوچکترین عدد صحیح k، به طوری که g دارای –kرنگ آمیزی دینامیکی باشد را عدد رنگی دینامیکی g می نامند و آنرا با نماد ?_2 (g) نمایش می دهند. مونت گمری حدس زده است که تمام گراف های منتظم ...
15 صفحه اولSpiral Meandering
The complex, so called meandering, dynamics of spiral waves in excitable media is examined from the point of view of bifurcation theory. A computational bifurcation analysis is made of spiral dynamics. It is shown that spiral meandering is organized in parameter space around a codimension-two point where a Hopf bifurcation from rotating waves interacts with symmetries on the plane. A simple mod...
متن کاملThe statistical mechanics of meandering
2014 We present a simple mathematical model to describe the statistical properties of the meandering of narrow streams on clean and smooth substrates. The model is shown to contain three different regimes, depending on the flow rate : (i) at low rates, the stream path is a timeindependent random walk ; (ii) for intermediate flow rates, static meanders appear. The onset of meandering is found to...
متن کاملA Simple Model of River Meandering and its Comparison to Natural Channels
We develop a new method for analysis of meandering channels based on planform sinuosity. This analysis objectively identifies three channel reach lengths based on sinuosity measured at those lengths: the length of typical, simple bends; the length of long, often compound bends; and the length of several bends in sequence that often evolve from compound bends to form multi-bend loops. These leng...
متن کاملInterdisciplinary Meandering in Science
I was a graduate student in mathematics at Princeton immediately following World War II, 1945–1947. In those days, with veterans of the war inundating universities, there was no option but to earn a Ph.D. within two years. My thesis research was in functional analysis, an area of abstract mathematics. My mentor was Professor S. Bochner, a distinguished contributor to harmonic analysis. My class...
