| Dec 23, 2019 at 14:05 | comment | added | Andrea Marino | msr * char of a non singleton subset exist only if the measure is (in modulo) <= 2 (disregarding delta!!) on any set. I am trying to find a formula that works in this case given the condition on the measure. | |
| Dec 23, 2019 at 13:32 | comment | added | Andrea Marino | @Tomek Kania: if you are interested in, I am finding sufficient (maybe also necessary, not sure about it), for the existence of tensor product. The idea basically is the following: you can split a delta additive function in a sum of a measure and a special linear combination of "characteristic" delta functions, which has measure delta on a prescribed subset and zero anywhere else. The tensor product is bilinear, so it is enough to study the tensor product of two characteristic functions (easy), and a measure with a char. I found out that msr * char of a singleton is a measure, and ... | |
