Abstract We find a simple relation between two-dimensional BPS N = 2 $$ \mathcal{N}=2 $$ superconformal blocks and bosonic Virasoro conformal blocks. which allows us to analyze the crossing equations for BPS 4-point functions in unitary (2. 2) superconformal theories numerically with semidefinite programming. We constrain gaps in the non-BPS spectrum through the operator product expan... http://jalyttlers.shop/product-category/plush-toys/
