Abstract: Let `L` be an even lattice of odd rank with discriminant group `L′/L`, and let `α,β∈ L′/L`. We prove the Weil bound for the Kloosterman sums `S _{α,β}(m,n,c)` of half-integral weight for the Weil Representation attached to L. We obtain this bound by proving an identity that relates a divisor sum of Kloosterman sums to a sparse exponential sum. This identity generalizes Kohnen's identity for plus space Kloosterman sums with the theta multiplier system.

Abstract: Several recent papers investigate the way in which the number of zeros of a complex-valued harmonic function can depend on its coefficients by analyzing specific simple families. These families share two features: (1) the critical curve separating the sense-preserving and sense-reversing regions is a circle, and (2) the image of that circle is a well-understood parametric curve. In such cases, the harmonic analogue of the Argument Principle can be applied to count the zeros. In this paper, we illustrate the strengths and limitations of these techniques; we construct a new family of complex-valued harmonic functions with poles having some of these features. We obtain detailed zero-counting theorems for two subfamilies, and we illustrate how to obtain less detailed zero-counting theorems for the general family.

Abstract: It is known that complex-valued harmonic polynomials of degree `n` can have more than `n` zeros. In Brilleslyper et. al., the authors consider a one-parameter family of complex-valued harmonic polynomials and determine, for different values of the real parameter, the number of zeros. We consider the same family but allow the parameter to be complex. As in the previous paper, our proof relies on the Argument Principle for Harmonic Functions and again requires us to find the winding number about the origin of a hypocycloid. The geometry is more complicated in this case, however. This additional complexity is reflected in the main theorem, which shows that the number of transitions in the number of zeros and the nature of these transitions depends on the argument of the complex parameter.

Abstract: We show that the projection of a product of two or three Eisenstein series of level one onto the cuspidal subspace is not an eigenform unless the dimension of the cuspidal subspace is one.

Abstract: In recent work, the first two authors constructed a generalized continued fraction called the `p`-continued fraction, characterized by the property that its convergents (a subsequence of the regular convergents) are best approximations with respect to the `L ^{p}` norm, where
