![]() ![]() Time permitting, we will sketch an application of our techniques in the context of ongoing joint work with T. We will start by studying the rather restricting yet convenient "strongly - monotone" case and then show how to generalise it to more general settings using an energy filtration argument due to K. The main step will be to use a neck-stretching argument to establish some energy lower bounds on certain trajectories realising differentials. Seidel (1996) for twists on surfaces, we gave an explicit description of the Floer cohomology of a Dehn twist in terms of Morse cohomology of some "sub-quotients" of M. Nowadays there are several methods to compute it, for example by using the Seidel exact triangle. This is based on joint work with Roger Casals and John Etnyre.ġ7 May Riccardo Pedrotti Title: Fixed point Floer cohomology of a Dehn twist in a monotone setting and in more general contexts Abstract: In this talk we will talk about the fixed point Floer cohomology of a Dehn twist. In this talk we will investigate whether a 4-dimensional tracker (with the necessary mathematical education) can determine the 3-dimensional creature that left the trace. We will discuss how the existence of destabilising exact triangles obstructs special Lagrangians, under some additional assumptions, using the technique of integration over moduli spaces.Ģ4 May Marc Kegel Title: Stein traces Abstract: Every Legendrian knot leaves a traces in the 4-dimensional symplectic world. ![]() I will focus on the exact case (Stein Calabi-Yau manifolds), and deal only with almost calibrated Lagrangians. 14 June Yang Li Title: The Thomas-Yau conjecture Abstract: The Thomas-Yau conjecture is an open-ended program to relate special Lagrangians to stability conditions in Floer theory, but the precise notion of stability is subject to many interpretations. I assume I can attach a plot for you here - if the attachment goes through, that's what the output looked like for me for m=1, c=1, k=1 (critically damped, which looks correct) with an initial stretch of 2 and velocity of 4.An online geometry seminar hosted via BBB on Tuesdays at (usually) 3 pm UTC.Ī link is sent to the e-mail list before each seminar. With that correction, your program seems to work. This forces Freemat to do the multiplication element-by-element instead of a matrix multiplication. after the first expression, like so: x=A*exp(-z*w*t.)*sin(wd*t+phi). To do an element-wise multiplication, which is what I assume you want, simply put a. This results from trying to multiply two matrices whose dimensions don't match up correctly, namely (A*exp(-z*w*t)) and (sin(wd*t+phi)). ![]() In C:/Users/tj/Desktop/Vibo_amo.m(Vibo_amo) at line 12Įrror: Requested matrix multiplication requires arguments to be conformant. If you try to run it as is, you'll come up with the error: Also, I gave your program a run, you have a debugging error in line 12. If you want to do further manipulation, you'll want to run it as a script (i.e.: take the first line out, define your variables inside the script explicitly, then you can source the script or just type its filename at the prompt). The arguments give you the ability to change the variables at will from the command line, but bear in mind that once the function has executed, you will not be left with any of your calculated variables from inside the function. You need to just type the function name with the arguments, like so: Because you specifically named this a function, to which you pass arguments, you can't execute it line-by-line with the source command. ![]()
