. However a lot of interesting mathematics falls out of trying to extend things that appear useful and simple. Its good to keep in mind that right now, the above expressiondoesn't make any sense. Until we give it a meaning, its just a collection of symbols. To avoid jumping the gun, ...
We initiate a systematic study of natural differential operators in Riemannian geometry whose leading symbols are not of Laplace type. In particular, we define a discrete leading symbol for such operators which may be computed pointwise, or from spectral asymptotics. We indicate how this can be ...

Professor Benjamin believes that, too often, mathematics is taught as nothing more than a collection of facts or techniques to be mastered without any real understanding. But instead of relying on formulas and the rote manipulation of symbols to solve problems, he explains the logic behind every ...

Presently, the only known nontrivial values are {\mathfrak {h}}_3=40 and {\mathfrak {h}}_4=120. The former value is due to Clebsch [9, 10]. We first learned it from [22, Prop. 5.2.2]. The latter value was computed by Vakil in [28]. The plane Hurwitz number {\mathfrak ...
