Let X be any infinite set endowed with the cofinite topology. Show that this topological space is T1 but is not T2. (Topology) Is advanced calculus the same as real analysis? List all real numbers x, for which the function is not continuous. z(x) = (2x-1)/(x^2 - 2x - 3) ...
$$\begin{aligned} \sigma _b = \cos (2\Delta \Theta )\sigma _z + \sin (2\Delta \Theta )\sigma _x = \left( \begin{matrix} \cos (2\Delta \Theta ) & \sin (2\Delta \Theta ) \\ \sin (2\Delta \Theta ) & -\cos (2\Delta \Theta ) \end{matrix}\right) , \end{aligned...
Prove that the union of countably many countable sets is countable. Why the empty set is a subset of every set? How to prove a set is compact? How do we know if a subset is compact? Prove that xdx=b2-a2/2 Suppose that f : X -->Y with A, B are subsets of X. Prove that ...
We prove a self-improvement property of a capacity density condition for a nonlocal Hajłasz gradient in complete geodesic spaces with a doubling measu
