Nov27 asked Show that $\operatorname{Hom}(S(-d),S)\cong S(d)$ where $S$ is polynomial ring? Nov26 comment Visulizing column/row space and null/left null space, A and x I didn't understand what you want! Nov26 accepted Cohomology groups of coherent sheaves for very small and very big twists. Nov26 answered Cohomology groups of coherent sheaves for very small and very big twists. Nov23 comment Cohomology groups of coherent sheaves for very small and very big twists. I searched it, and the theorem says there is $m_0$ such that for all $m \geq m_0$ we have $\mathcal{F}(m)= \mathcal{O}(m) \otimes \mathcal{F}$ is globally generated, and your answer is exactly that by induction. I wish that you recommend me a book to source to read how globally generating would imply that $\mathcal{F}(m)=0$. Nov23 comment Cohomology groups of coherent sheaves for very small and very big twists. Thanks Alex for comments, I will follow them, but I have a question, is $m$ in your comment unique, and does $\mathcal{O}(m)\otimes \mathcal{F}$ globally generated implies that $\mathcal{O}(m+1) \otimes \mathcal{F}$ is globally generated. because one asks what if $m$ in your comment is less than $d$ for which $h^0\mathcal{F}(d)= 0$. Nov23 comment Cohomology groups of coherent sheaves for very small and very big twists.
