Double bubble plumbings and two-curve flops
نویسندگان
چکیده
Abstract We discuss the symplectic topology of Stein manifolds obtained by plumbing two 3-dimensional spheres along a circle. These spaces are related, at derived level and working in characteristic determined specific geometry, to local threefolds which contain floppable $$(-1,-1)$$ ( - 1 , ) -curves meeting point. Using contraction algebras we classify spherical objects on B-side, derive topological consequences including complete description homology classes realised graded exact Lagrangians.

The Double Bubble Problem on the Flat Two-torus
We characterize the perimeter-minimizing double bubbles on all flat two-tori and, as corollaries, on the flat infinite cylinder and the flat infinite strip with free boundary. Specifically, we show that there are five distinct types of minimizers on flat two-tori, depending on the areas to be enclosed.
متن کاملThe double bubble sign
The double bubble sign in neonates is seen on plain abdominal radiographs in a variety of conditions. It represents gas distended dilated stomach and proximal duodenum, and implies congenital proximal bowel obstruction. A newborn with a double bubble and no distal bowel gas can be presumed to have duodenal atresia and in most cases no further imaging is required. If double bubble is present wit...
متن کاملThe Double Bubble Conjecture
The classical isoperimetric inequality states that the surface of smallest area enclosing a given volume in R3 is a sphere. We show that the least area surface enclosing two equal volumes is a double bubble, a surface made of two pieces of round spheres separated by a flat disk, meeting along a single circle at an angle of 2π/3.
متن کاملA New Design for Double Edge Triggered Flip-flops
The logic construction of a double-edge-triggered (DET) flip-flop, which can receive input signal at two levels of the clock, is analyzed and a new circuit design of CMOS DET flip-flop is proposed. Simulation using SPICE and a 1 micron technology shows that this DET flip-flop has ideal logic functionality, a simpler structure, lower delay time and higher maximum data rate compared to other exis...
