Cycles Definition and 158 Threads

This is a serious question. I'm not posting it to be vulgar or obsene. :confused: My sisters, our mother, and I are noticing that our monthly cycles are almost 100% in sync with each other. We thought this was pretty weird. Mainly because our cycles used to be at completely different times of...

can anyone explain me the technique to decompose a random n-cycle into a bucnh of 2 cycles. Thanks in advance.

I'd imagine this will get relegated to theory developement, but here goes anyways. Looking at some of the charts for solor cycles it's clear to see the 11 year cycle. But this cycle seems to grow stronger with every repeation. It then resets to a low point a starts again. Now, I admit, I know...

Show that a 3 cycle(a,b,c) in Sn has order 3. Show that a product of disjoint transpositions (a,b)(c,d) in Sn has order 2. Find the order of (a,b)(x,y,z) in Sn, if this is a product of disjoint cycles. Apply this to tell the orders of all permutations in A4.

Hopefully this is a quick questions. I'm trying to describe what an attracting heteroclinic cycle is but not sure really how to describe it or what it means. I have a 3-dimensional population model x(t), y(t), z(t), which has a phase portrait that spirals from one equilibrium point to three...

The water and sedimentary cycles are interrelated in many ways, Would you please help me to identify the interactions between : sedimentary and tectonic, sedimentary and igneous, igneous and tectonic, water and tectonic ? Thank you very much in advance,

Could you please tell me their life cycles ? Does anyone of you work with worms daily ? I am sorry, i mean your research, your job ? Thank you very much

I observed with several electronic devices (primarily romote controls) which use infrared light emitting diodes (IR-LEDs) to send data is that with some, if the LED is viewed closely and carefully enough you can see a red light flash when being used. I know that IR light is invisible, and I'm...
