I run simulations on srim software and I need to plot the sputter yield vs. target voltage
We are using a handheld spincoating system for wound dressing from the brand SpinCare™ (nanomedic.com). The instrument has fixed features that we cannot change. Basically, the voltage is fixed...

Is $TT^*$ (or $T^*T$) densely defined if $T$ is a densely defined and symmetric linear operator? I feel this is untrue, but do you have a counterexample? Thanks, Hichem

Let $A$ be a densely defined symmetric (unclosed) operator and let $B\in B(H)$ be positive. I know that if $\overline{A}B$ is normal, then $AB$ need not be normal. My question is: If $AB$ is...

Let $B\in B(H)$ be self-adjoint and let $A$ be a densely defined symmetric (and closed if needed) operator such that $A^2$ is densely defined. If $BA^2\subset A^2B$ say, is there a result which...
